The team from Intermountain Windows & Doors was great. I was happy with the timely communications from the office prior to the installation. The window installers were pleasant and efficient, and I was very pleased with their work and the clean-up afterwards. Service: Window installation

I needed a window, slider and exterior door for a remodel. I tried Lowe's and Home Depot and couldn't even find someone to help me. So I called Intermountain Glass and got a call back within 10 minutes. Bradley Moon was so helpful. He told me to go to the showroom in Bothell and look around. From the moment I walked in, Hillary Dixon greeted me and helped me find what I was looking for.

She emailed Bradley the information and he had quotes for me within a few minutes. I am so glad I went to Intermountain. Great customer service is hard to come by, but Intermountain delivers!

After working with other companies for other window projects add and feeling less than satisfied, this is now our go to glass company. The team of Tony and Nelson were efficient, on time, focused and precise when installing two single hung windows in our home. They took time after the installation to explain everything that they did and tell us about our warranties.

They also gave us some suggestions for maintaining things around our windows. Really nice guys! And the company is super responsive for any questions that we have had And they have been accommodating for our schedule. They had super competitive prices for everything that we had quoted too.

We replaced 8 windows in our home and while the finished product looks pretty good, the path to there was frustrating at times. We ordered our windows last May (2021) and we just got the last window installed last week (January 2022). There was a general lack of communication throughout the process and expectations were not set appropriately. Upfront, we were told our windows would all be installed by August 2021.

With a few mis-measurements and backordered windows, the project was finally completed in January 2022. Giving 4 stars because while the process was frustrating, the company worked with us to make things right. They were very kind throughout the process and it is clear they take pride in their work and the delivery of their windows. The onsite team did a nice job installing the windows, and the completed project looks good.

I can't say enough good things about our installer. He was friendly, informative, patient and knowledgeable. And most importantly, he did stellar work. The doors we got are good quality, although I found small imperfections here and there. I chose to paint the entry door myself which was a tedious job because of the plastic trim which flakes paint easily.

But I also heard the factory paint doesn't look as nice as hand painting. As for customer service, everyone is nice and professional. There was an issue when our project got transferred from sales to production and our project got dropped. I was told they would let us know in 4-6 weeks when the doors were manufactured. 8 weeks had gone by and I hadn't heard from anyone so I called and apparently they had the doors but didn't realize. They fit us in for install a couple of weeks later. I understand it was due to a change of employees and those things happen. So overall I'm really happy with Intermountain.

We used Intermountain to replace two exterior doors. The communication from initial contact through install was phenomenal. My home had a wonky threshold situation and our installer did an amazing job of seeing the issue. He made sure the threshold transition was done in the most unintrusive manner. This included ordering a part. The installer did a great job of communicating when new part should arrive and when that did not happen he asked for good days for him to come back when part arrived.

I did not have to call to find out when installer would return. We had used Intermountain prior to it being bought by the current owners for whole home window replacement. I found the current Customer service to be what it was before if not better.

Intermountain is my go to for window and door install. They are timely, professional, do good work, and are a good value. Even with supply chain hurdles these days they are up front with how long things take and you never feel like you are being ignored during the wait for materials and scheduling. We have had a custom size patio door and several custom windows done and all have been great.

We originally ordered from IMG because we were wary of all the problems we heard about with box stores, they had a nice quoting process, and were not pushing their own custom product. That was where the pleasantness ended. At Inter Mountain Glass hours of your time are not worth a 2 minute phone call by them. They missed at least 3 appointments with us, with no phone call.

We would come home and sit, then after the arrival window call and say you were supposed to be here. 'Oh, yea we can't make it.' Well, if you knew you couldn't make it you should have called so we are not rushing out of work or something else just to wait for nothing. They missed the measurement appointment. They missed an install day.

And they missed a post-install inspection after we complained about damage and poor installation. They ended up doing a measurement visit when we were not home, and failed miserably. We had 7 windows and a door, with 4 different window sizes. Two of the windows were off by at least 6 inches. We can only guess they didn't measure them and there was zero quality control to compare the measurements to the quote and see that they were very different. Also, the door was too short by at least an inch.

Which they tried to convince us to just install anyway, even though it would be a major tripping hazard because they wanted to shim it UP and have the lip raised about 2" above the floor. At least we directly didn't pay for their screw up? So now instead of getting everything installed in 2 consecutive days we have a month between installations, with lots of additional furniture moving, etc.

Then they just don't show up to install on the second day. Excuse - "ohh, we are too far away and we are not going to make it I guess, because we double booked." Gee. Thanks. When they finally came into install the last stuff they messed up a brand new carpet - it was left unattached to the tack strip in some areas, and ballooning up in another area (instead of stretched tight, how it was installed).

Not to mention scratches and dents all around the interior of the house where they were operating. Also, almost every install needed to have the caulking fixed after because it was cracking and pulling away, not actually sealing anything. And once they did finally install the SCREEN door, they did so without a screen. So now we can't have the door open to cool things off on the hottest days of the year.

We would have much preferred they wait to install the door until it had a screen. We could at least use the old screen door. But they didn't so much as inform us there was no screen until after everything was done. With all the damage and the screwed up carpet we called and complained. So they sent out someone to inspect it. Of course he misses his arrival window.

They were called to ask where he was, since we had several no-shows from them already and we were assured he would be there. Thankfully he was less than 30 minutes late, but knowing he was going to be late, a quick call an hour earlier would have been simple. Finally, for weeks after both installations I was finding debris from the installation all over the yard.

Not just bits of wood, but small sharp metal parts, debris from caulking tubes, etc. I even found a whole (empty) caulk tube in the bushes! They don't do much of a clean up and it seems like they just toss small things over their shoulder into yards where children run around barefoot. IMG demonstrated a complete lack of care for our time and our property. I would NOT recommend going with them. I wish we had spent ~20% more and gotten windows from somewhere else.

They were all reliable and professional in every step; their initial visit for the design ideas, and material decision, sending proposal, site visit to get site measurement, scheduling and installation. The lead time was long for the windows but it is the new norm right now; there is no immediate service you can get during the pandemic. We are happy about their overall work. Thank you to the whole team.

I usually never write a review, but I feel that I need to share a Great company! I have had 5 windows put in plus a sliding glass door and screens. They were here when they were supposed to be, clean and neat, workers were professional, and went like clock work. I have had 4 other neighbors use this Bothell company so if you are in the hood this is a company to use. Terry Top Notch

I've worked with InterMountain Glass many times over the years. Always a pleasure. Customer service and safety is their top priority. The quality of products along with a very competitive price is very nice. I look forward to using them again to update our new house.

I highly recommend this company! We had 2 windows to replace with failed seals that were fogged. I looked into replacing one of them a few years ago and the estimate from a different company was sky high. And they really didn't want to come out for one window. Now that I had 2, I called Intermountain and I am SO glad I did. They are professional, responsive and have great communication.

They came out and measured quickly and the windows were ready to install in a few weeks. The installer was awesome, friendly, super quick and the finished windows are beautiful! So glad I found them, my house is just over 20 years old and I'm sure more window seals will fail in the next few years and I'll be going to Intermountain every time!

I had a great experience working with Randy and team at Intermountain Glass. Their bid was competitive and Randy was very responsive as I asked many questions and adjusted the scope of the project, though we eventually ended up with just a patio door install, from Milgard. The install team worked quickly and cleanly, even as it was raining outside. Very good overall, would highly recommend working with them in the future!

For our project we sought: - replacing all windows and doors in our house with thin-bevel, energy-efficient windows with reliable manufacturer support, - changing the shape of several existing windows, - cutting out a new large 8ft wide door to our garden, - get a different combination of tempered glass, double low e, screens, double-hung windows depending on its location Met 3 companies, but only IMG was able to meet our goals.

We met several times to complete all measurements, discuss variants, discuss necessary preparations. When the installation day came, we were able to - work out a solid plan for each installation day, giving us ability to continue to work from home - organize work around window installation and electrical wiring modifications (necessary when cutting out new door) - talk through finishing options The crew made sure to - above all - leave the place clean each day, including dusting the garage where a lot of wood was cut, or marks on difficult to access walls where they placed a ladder - respect our need to work or join remote meetings when we needed to - reorganizing their work so that they would not be idling - work fast and discuss with us plan for the current and upcoming day.

There were a few delays in the process, but with the scale of work i would say nothing out of the ordinary. The result - one of the darkest, most avoided rooms is now the most beloved rooms in our house, with a large window facing our garden - our house is a lot warmer - it took us just one weekend to make everything look as if nothing ever happened. Thank you for transforming our house. We're glad we found you.

So, it took four attempts before Intermountain Glass got our warranty replacement window correct. The first time they found a flaw in the glass. The second try they found thin strands of glue between the two panes. The third attempt they actually got the dimensions wrong. Finally, on the fourth try, they got it right! Next point. The installation was done by Frank.

I had tried to protect my garlic plants under the window, but Frank just threw his tarp across them and said, "I'll buy you some garlic myself". Frank did not wear a COVID mask at any point while on the job site even during discussions with our contractors - to whom he was also short and rude. Did our window get replaced? Yes. Eventually. After five cancelled appointments. Would we recommend this company? Not very likely.

These gentlemen were awesome. We had 12 forty year old windows to replace, they came for a quote in one day, gave us the best deal with the best warranty. The workers arrived early, worked very professionally and even cleaned up after themselves. My new windows are beautiful and we couldn't be more pleased. I would recommend them to everyone!

After a long discussion with Andy, one of the owners, he assured me that my experience was not the norm with their company. He made sure that the missing part was taken care of in the next couple of days after I spoke with him. The technition that came out, Rhett, was great and got it fixed quickly. I asked about an old slider door giving us problems and he told me the fix was simple and they would order the part.

I was communitcated with about each step of the process to fixing the door and Rhett even had some extra time and came over early to fix it. Our door works better than we can ever remember! I can't give a 5, due to our previous experience, but this time around, my faith was renewed in this company.

I had a moldy old kitchen garden window. Intermountain replaced it with a beautiful window. I thought I'd have to hire a painter to paint around the edges of their replacement, both inside and out, but they didn't leave a scratch. The team they sent, Dave and Austin, were in and out much quicker than I thought and really knew their job. Dave even took the time to look at a couple of my older windows that always get stuck and shared some great advice. Great job. Thanks.

Installation was fine, windows took about 6 weeks after order for delivery. Sales and customer service leaves something to be desired.

After posting this review I received correspondence stating they would now come out and do the repair. When I declined their services they requested me to take down my review or to write an addendum.

We needed an old failing garden window removed and replaced with a Milguard slider. We called and visited other businesses. No one would come out to measure except Intermountain. We received a clear estimate. There was excellent follow through scheduling and completing the work. The crew sealed the opening while working to avoid dust in the house. The crew explained the condition of the siding, how they seal it to be sure moisture does not get in. We have confidence in their work.

We got estimates from at least three (3) window companies to have all the windows in our older Ballard home replaced. Intermountain Glass came highly recommended by a neighbor/ contractor who had used them before and mentioned they were family owned and employed their own installers, which he said was important. The estimate was not the lowest--ONLY because another company kept lowering their bid (three times) in order to land the job--never a good sign. Intermountain Glass totally checked out through BBB and others, and we had all the windows (14 total) in the home replaced, including a number of rather large picture windows and several tricky scenarios tackled.

We had some trim/flashing replaced on the house and changed colors; they were very patient with our questions and pondering. The final cost was great, and the windows were far more impressive than we ever realized. We could not believe how much they made a difference in the noise reduction from traffic on the street, as well as keeping the house warm. Amazing! Installers were polite and professional, and they came out to check the job and also did another trip to double check an item we asked about.

Several years later, the windows still look great and the work is good. Windows are a big investment, so it's important to get the right company. This company, which doesn't advertise, is a hidden gem.

Be careful when you signs contract because I just learned that our windows are slide into the frame with out real frames, even though it's life time warranty, they tell you you signed to have the windows installed that way! But we found out all the screws are not even screwed into anything but air when we open up some siding from the outside, and eventually the windows will sag.

They are betting on people move every 3-5 years so the warranty will not be transferable to the new owners, case closed! But if it's not installed right no matter what I signed 3 years ago, it is not safe. Hopefully they will come make it right even they don't want to, I will give another rating after things are fixed.
