Mike and his crew were good to work with. They built an addition on my 1925 house in challenging weather and it turned out great; and at a fair price. Would recommend them for your building project.

Mike and his professional crew removed our dilapidated old deck and rebuilt us a beautiful, safe and functional new deck. They also did some drywall work inside our home. They are reasonable with pricing and leave everything just as they find it, even cleaner. They fit the work into our timeline and had an amazing follow-up. Highly recommend them!!!

I can't say enough good things about Mike and his crew. They remodeled my bedroom and installed a beautiful bathroom in my loft area. They are very talented and professional. I enjoyed the experience and found the perfect company to continue doing business with. We're already making plans for the next steps in our home remodel. I can honestly say Mike, Casey, and the rest of the crew are the best at what they do.

I had Mike build two different covers for my patio. I couldn't be more happy with the work. The craftsmanship and the finished product were exactly what I had envisioned. His crew was on time everyday and made sure everything was cleaned up and put back in place. I can't recommend him and his crew enough. I have more projects planned around the house, and he will be the only person I will contact for the work. I know he will do the job at a fair price.

Working with M. Armstrong Construction LLC has been, by far, the most pleasant part of our water leak ordeal. Mike and Trystan were a pleasure to work with — professional, communicative, and patient as we navigated the insurance process. KC, Sidney, and Ryan made the experience easy and pleasant with their efficiency, attention to detail, and courteous, friendly demeanor. We are thrilled with how beautifully they put everything back together and couldn’t be happier. Highly recommend! - Many Thanks, The Petersens

We recently had M Armstrong Construction replace an old tub/shower enclosure with a new Handicap Accessible WalkIn Shower in our Master Bath. From start to finish Mike and his crew were nothing but professional. The bid for the work was reasonable and even when unknown issues came up during the job, the increase in price was extremely reasonable. The 2 man crew lead by KC was always on time, were completely professional at all times, kept us informed and kept the job site clean and our Master Bedroom was kept clean, even during drywall work. I can’t say enough good things about M Armstrong Construction and recommend them with no hesitation. Thanks Mike & KC

Mike came in a reasonable amount of time and gave me an estimate to build a deck cover at my home. The cost was reasonable and the crew who built it was efficient and courteous. KC the foreman really did a stellar job.

We had Mike install new railings to the deck of our house prior to listing it. Everything went smoothly from beginning to end.They turned out very nice and will add value to our home. Mike is very easy to work with and his prices are fair. We highly recommend.

We hired Mike to replace our siding and insulate our house. He and his crew were always professional, on time, and did a great job. Our house looks great and stays much warmer. We have already booked Mike and his crew to come back to do another job.

We hired M. Armstrong construction for a roof & skylight replacement July 2025. Mike's team is professional, knowledgeable, and responsible. From the beginning Mike was very responsive and quick to complete the quote process and communicated same quickly. They were timely and on schedule throughout the process. Great work, and since we've just had our first rain,,,,,NO leaks! Great company, thank you Mike and team!

I hired Mike to take 2 bedrooms and make a Master Suit for me.That included a new shower, toilet and Vanity. It also included a large walk-in closet. Mike's price for the work was very reasonable, and was a third the cost I had been quoted by other contractors in the area. His crew work very fast and compleated the job on time. I will use Mike and his crew again for future projects.

CALL ARMSTRONG FIRST! Save yourself time and money!!!! I contacted several construction companies at once in a 50 mile radius…Some showed up to give us a quote then never heard back. Some never called me back, some gave me quotes that were just outrageous. Armstrong construction showed after contracting them and gave me a quote the next day, that was FAIR. Mike (the owner & GC) explained they were extremely busy but would get my job done for me even if was done on the weekend. I desperately needed a bathtub put into my master bathroom. Mike and his crew were just amazing, they squeezed me in and got started as soon as the bath tub arrived. KC was the head of the project he did an amazing job, he showed up on time was so respectful, clean in work space and just a delight to talk to. I couldn’t be more pleased with my new bath tub and the tile work is perfect. Mike followed up even weeks after they completed there job just to ask how I was feeling and how I was enjoying my new bath tub. The knowledge, compassion and efficiency of Armstrong Construction surpassed my expectations. We have more projects coming up and will be using them again.

Contacted Mike about correcting an issue with our post and beam foundation. Home was built in 1960, support posts had degraded and sunk. One side of the house was noticeably lower than the other. Mike provided a reasonable estimate and showed up on the date and time he said he would. Mike’s crew was knowledgeable and hard working. Job was completed quickly and more than met our expectations. We highly recommend M.Armstrong Construction.

Mike and his team are amazing. They have done many projects for me and I couldn’t be happier with the work. Big or small projects this time does it all!

Mike and his crew were fantastic. I had a tree fall and hit my garage causing a fair amount of damage. They came out immediately after contacting them, and had it fixed in a matter of days. There is no evidence that my garage was ever damaged. Excellent communication, top quality worksmanship, and very fairly priced. I cannot recommend these guys enough!

I cannot say enough about the job Casey(Armstrong construction) did putting in a shower. They were there when they said, cleaned up any mess and hauled off the trash as soon as they were done. The room looks so good walls, flooring and moved fixture. The price was what they quoted. I will use them again if needed.

We’d been trying to get our roof replaced for nearly a year. Tired of waiting, we contacted Mike. He is organized, professional, calls when he says he will. He got the job done in l as than a week (as he said). His crew are very considerate of our needs. Very happy with their work. Sue in Lakeside.

M Armstrong Construction is a truly legit awesome company to work with. I would highly recommend him & his team. I had an old wooden wheelchair ramp on the front of my house that needed to be removed and a new set of steps with railings up to my deck built. I needed the lattice work on the deck painted & installed, as well as a new gate at the top of the stairs. I also wanted a pergola built over a patio area that matched the roof on my deck. Mike was very responsive at all times and kept in contact throughout the whole project. He told me it would take 3 days and that’s exactly what it took. His team showed up on time, got right to work and cleaned up the job site every evening, I couldn’t even tell they had been there other than the completed work. Everything turned out exactly as I wanted, it looks fabulous!!!

Due to water damage to our house siding, we hired Mike Armstrong Construction to correct this problem, which he did in record time. He listened to our concerns and what we thought could be changed. He has a great crew that care and paid attention to all details involved. I highly recommend them!

We recently had them change out a shower and remove a tub in our master bathroom. They were here on time every morning to begin work and clean up their work area every single evening. They did a fantastic job. The team of guys that were here daily were knowledgeable and got the work done VERY quickly. Finding a good contractor has been difficult. These guys were amazing. Even called a couple of days later to ensure that we were happy and didn't have any issues with the work. We will most definitely have them back for a few other projects.

Michael just does great work. First time using him and his people and we were not disappointed. He made an office for us, put up walls, doors, painted walls, baseboards etc The work was very professional and he came everyday on time. He made sure we were happy and satisfied with the work. We highly recommend him. Karen and Russ

Michael and his team did a terrific job on our hillside deck and stair project for our cabin, we moved to Idaho before the project got underway and I never once felt any lack of communication, his crew was great with offering ideas and options throughout the build and Michael kept me updated with pics and text messages so I didn't feel like i had to be there... We would definitely give Michael a call for our next project! Mike & Lori Burton
