We hired Side-Pro to reside our home and they were amazing to work with. Quick to answer all questions, clear on their estimate and stuck to the contact and delivered on time. The crews doing the work were great, being on time and respectful of the house and family related stuff we had going on. I highly recommend Side-Pro for any project and would be thrilled to work with them again.

I needed a hole cut in the siding of my brand new house to mount a light fixture in my back yard patio. I called Side Pro and talked to Sam who said they would be happy to do the job. In less than a week he sent one of his workers who did an excellent job of cutting a hole and mounting a block for the light. The work was done quickly (35 minutes) and looks perfect. I really appreciated the professionalism from the office, to the scheduler, to the actual worker (Abel), to the person who invoiced the job. And the price was very reasonable. I would highly recommend Side Pro and will definitely use them again.

We used Side Pro on our private new construction build, and it was such a positive experience. Excellent communication and quality work. We were very happy with the result. We even had them come back out for some late change orders and I was surprised by how quickly they turned them around. Very pleased, and will absolutely use in the future.

Side-Pro did an amazing job on our home! We added 800 sq ft to our existing home and they did the roof, windows, siding, gutters, and interior paint! We are waiting for nicer weather for the exterior paint, I will try and remember to post a pic! Every one of their employees were professional and courteous! It was very clear that they all cared about doing high quality work. They cleaned up at the end of each day like they were never here. We were so impressed and would definitely work with them again!

I used Side-Pro to side a custom home I built in Seattle. They provided a detailed bid including change orders listed out. Provided a schedule and scope of work that they greatly exceeded. I would highly recommend them.

Side-Pro Exteriors completed our exterior siding project and we could not be more pleased. In our experience, their team was reliable, thorough, responsive and more than capable of professional executing all of our exterior siding needs. We will not hesitate to continue working with Side-Pro Exteriors in the future and look forward to our next project together.

This is the first ever online review I have ever done, so my review should be weighted accordingly. After receiving many bids on our roof replacement, siding and window needs we were excited to work with Side-Pro. Their bid was delivered with every detail needed to describe the process and the expectations of the work. It came in a binder type form with pictures of every process to be preformed. Really the best bid I have ever seen displayed this way! It is clear after looking at it that they know what their doing and take care of waterproofing the correct/professional way. After and during the job I had easy access to the supervisor at hand. Everything was done perfectly and we no longer have a leaking roof. We had them install new gutters as well and now the house looks brand new. I already have future projects that have their name on it.) Thanks Side-Pro!

Side-Pro Exteriors is a very professional company that performs so many functions that normally require people to hire several different companies. In 2022, they replaced a roof on my 2-story house that included demolition & installation of new 25-year asphalt composition roofing, replacing damaged plywood underlayment, new soffits, gutters & downspouts. In 2023 they will demo 30+ year old windows, install new energy efficient windows, demo existing cedar siding & install new Hardie Board Siding & painting of the entire exterior. They were & are very efficient, clean & have great craftsmanship. I will always recommend them.

Used Side-Pro for a nearly full siding replacement of a commercial building. Very much appreciate the thoroughness of the walk through during the estimate, which included design and material suggestions to modernize the façade. Never felt I was being upsold as Russell gave several suggestion on how to be cost-effective in the project. I received an extremely detailed quote with line item breakdowns and photos. The actual work was done with care and with good communication. End result was a visually-refreshed building. I am so confident in their work, I've already engaged them to handle a separate roof issue at the same building and some work at my personal home.

Well, I wish I could leave a 5-star review, but there were some pretty serious challenges with our project... mostly due to serious communication issues on Side-Pro's end. Choosing to go with Side-Pro was easy as Matt was great to work with on negotiating and setting up the contract. He's very down to earth and very responsive. When it came time to do the siding, Duane and his team were great. Duane told me to contact him if there was anything that would prevent getting a 5-star review. I took this seriously and this part of the process went very smoothly. There are a few small issues with the siding, but nothing overly noticeable, so we are pretty happy with the work done there. Then, 10 weeks passed with very little communication from the painting team. I had to ask repeatedly about getting on the schedule and never received initial contact from Mo until I asked for the manager's name. I said I understood the challenges with the weather, I just wanted to know if our contract would be upheld at that point. Once I asked for the manager's name, we were magically on the schedule for later that week. Why should it come to that? I find it sad that, by waiting patiently, I was being ignored. The painting went smoothly and the actual team was really nice and extremely hard working. My final complaint falls with the billing department. We had financing, but since there were some repairs that fell outside of the initial bid, we also had to pay a balance. We were sent invoices with incorrect numbers constantly and, even after we had sent in checks, we were still given incorrect numbers. I pointed out how confusing this was and tried to tell Rena that she was sending incorrect information and she just told me to have a nice week. Very, very poor communication and I'm glad we were paying attention or we would have overpaid a significant amount. Overall, the house looks great, so I give them four stars. If you aren't a firm and organized communicator, however, this might not be the right choice for your siding project.

I reached out to Side-Pro for an independent evaluation of siding work done by another company since we had already identified several issues on our own but our siding/construction knowledge is very limited. Russell was happy to assist and was very thorough in his review and explanation of the issues he identified. I also learned that Side-Pro is unique in having all of its crew as company employees. At other companies everything is contracted out so you can't count on quality. If I could go back, I would have chosen Side-Pro in the first place and absolutely recommend you do the same. The quote was comparable to the company we went with and I am mad at myself for trying to save a few bucks at the expense of my house!

We contracted with Side-Pro to replace all of the cedar siding on our house with HardiePlank, paint the trim, and install new gutters. We signed a contract on 2021-06-25 knowing that they were booked through September, but Side-Pro was the best company we'd talked to so we were happy to wait.They started in October, and Duane the foreman and his crew(s) were uniformly wonderful to work with. Teodore and another worker were responsible for removing all the existing siding. They showed me several areas of concern throughout and gave me a chance to fix things up (mostly installing insulation where it was missing or had been destroyed) before they moved on with installing the housewrap and siding. They put new, flush-mounted blocks in for all our hose bibbs, outlets, and lights as well that look so beautiful compared to what was there previously. Teodore even installed a custom laundry vent door for us instead of the one they had brought, something they really didn't have to do. Throughout they were extremely communicative, always on time, and some of the cleanest and nicest contractors we've ever had the pleasure to work with. If you're going to have strangers all over your house for a week you want them to be awesome, and Duane and his crews always were.Due to fall/winter weather in WA we ended up getting gutters before paint, but the gutter crew that Side-Pro sent out was from "Above All Gutter Guys" (yelp.com/biz/above-all-g…) and they were likewise excellent to work with. The gutters look so crisp, they do a great job funneling water away from our house, and Carlos suggested some new gutter runs we hadn't considered before that made them significantly less noticeable in our backyard. Another great experience.Their paint lead Mo was also great to work with. There was some scheduling complexity due to weather but he let us know exactly what they were waiting for weather-wise and always kept us updated on when they were coming over to paint. Mo and his crew worked fast and did a great job on all the trim and roof edges. They cleaned everything before they painted it and our trim has never looked better.We had a heat pump installed shortly after the siding went on, and due to a miscommunication with that contractor ended up with a 3" hole in our brand-new siding that was empty. We asked Duane about it and he sent out his crew to fix despite it not being their fault or covered in our contract. That sort of customer service is incredibly hard to find these days and the crew did a great job sealing the hole given some gnarly spacing constraints.Throughout this process we were extremely impressed with Side-Pro, we wouldn't hesitate to call them back out.

We recently had our siding replace d by side pro. They replaced all of our siding, fascia boards, gutters, and painted. They were responsive and understanding from the beginning to end. They helped us come up with some accent siding ideas that made our house look modern and less like a beige box like it did before.We found water damage, insect damage, missing flashing, and missing house wrap after they removed the old siding. The SidePro team repaired and replaced as they went upgrading everything, installing new wrap, flashing around vents, adding flashing where the deck met the house, new back plates for electronics and even repaired all the water and insect damage. They even caulked everything. We had them also install a pergola over the garage as well and they did a great job designing that too. The hardiplank material that they used is high quality and everything came out great. The new gutters work so much better. We had them install gutter guards as well and it made a huge difference. Painting went pretty fast and came out exactly as we had hoped. After the house vents were blocked after being painted over, they even came back out and fixed them. Their entire crew was great from beginning to end and our house looks like a brand new house.We wouldn't hesitate to recommend them for any of these services. We had a great experience working with side pro.

Side-Pro's is the best in the business! The value and level of expertise, honesty and integrity made them our #1 pick to have our siding and windows replaced three years ago. We just had a new fireplace installed and the siding on the bump out where the exhaust exited the house needed to be replaced. It was about 4-5 pieces total. Side-Pro's came back out and replaced the HardiPlank for us in no time! Great people! Great service!

Side-Pro did a FANTASTIC job installing the Cemplank siding and Hardieboard trim on our new shop. The price was great and the work was top-notch. The two gentlemen doing the work were efficient and professional. Communication with DJ, the project advisor/estimator was very good. Overall I am very pleased and will definitely use them again! Highly recommended.

I am VERY satisfied! I called for a repair job. Several other companies either would not give an estimate, or could not do so for several months. I got the job done, as requested, within a couple weeks. Karl their repair specialist is pleasant to work with, as well as competent.

I needed crawl space vents installed with very short notice. Side-Pro set up an appointment and got the work done in a matter of days! The contractor who did the work busted his butt and was very nice. The work is excellent.
