We had a major flood in a mobile home. The bathroom, bedroom and part of the dining room had to be ripped back to the studs.That’s when GFM Construction came in. Everything had to be reconstructed, floors, walls, closets and we had a walk in shower installed in place of a tub. They did a beautiful job! Very easy to work with. Very hard workers and considering the amount of work - were very quick. The price was very good. Please consider them for any construction needs

We have had great experiences with GFM. I highly recommend them! We have worked with them on two projects now, and likely more in the future. Our kitchen/laundry room flooded and GFM was a great partner in the repair process - working with our insurance, very detailed in their work & invoice, and rebuilding with excellence. Their onsite team was great. We had such a good experience that we reached out to them to help with a personal project where we converted our large backyard shed into an office space. Alex is quick to communicate, friendly, and so knowledgeable. I highly recommend them!

Thanks so much to Alex Belonenko and his team at GFM Construction. They took a tough job at my elderly Dad's home upstairs and downstairs - dealing with asbestos, mold, mildew, plumbing, electrical, flooring replacement, and other major problems - and got the job completed after numerous lengthy insurance delays. Alex and his team were polite, professional, and kept me and my Dad informed on their progress regularly. Their finished work looked real good.

I would definitely recommend GFM Construction for high quality residential work.

Much appreciated.

GFM did a excellent job restoring our house from water damage. Alex and his team were extremely helpful, courteous, and fair in all steps of the construction process. They were very helpful in navigating the insurance claim process as well. The quality of work was top notch, and they made sure we were satisfied with the final product. Highly recommend using GFM Construction.

I highly recommend GFM Construction. The team recently remodeled my master bath, hall bath, and laundry room. The quality of work, especially the tile work and custom shower, is fantastic. The crew was timely, kept the work area clean, and did a good job communicating with me on any challenges that came up (like in all construction projects!). I’m already planning my next project with GFM. As someone who has done a lot of home improvement over the years, I can say with confidence that this is a company can be trusted to get the job done and done very well.

We had a roof leak into our bathroom. From the initial consultation to the final walkthrough, Alex and the GFM team demonstrated professionalism and expertise. Their transparent pricing eliminated surprises, while their cleanliness and quality of work showed respect for our home. What truly impressed us was how they handled unexpected challenges and other minor home fixes, offering creative solutions without compromising quality. We recommend the GFM team for major home repair projects or tackling small repairs.

We needed a lot of repairs to our basement after a sewage back up. We were referred to GFM by our water mitigation company. Alex worked tirelessly with our insurance company to get everything approved, and his team did excellent work to restore our home to a beautiful condition. From drywall to flooring, a shower install and more, they did quality work. They also worked with us to repair things not covered by insurance. I would highly recommend! I will definitely reach out to them again for future needs!

It has been an amazing experience working with Alex and GFM Construction! He helped me to repair my bathroom after water damage of a leaking pipe! He was great at navigating the insurance refund!

Thank you!

Working with Alex and staff of GFM Construction LLC was indeed a good experience. They even dealt directly with our insurance company for cost estimates as this was a property damage claim job. They and company were responsible for phase 2 for the finished room at the end of our garage that had received significant water damage in an exterior wall and part of the ceiling from a leaking patio roof in late summer 2024. After the phase 1 was completed by the water mitigation company, Eco Water Restoration LLC, GFM Construction replaced insulation, drywall, drywall finish, and final painting. The room looks like it did before all the water damage. And they cooperated with us to use Low VOC paint as well. I have already recommended GFM Construction to a friend of mine in Seattle. I wish them well.

Alex and his team were phenomenal! Very professional and kind. GFM Construction came highly recommended after I had a leak in my stairwell – they took care of drywall and paint while navigating a set of floating stairs. They were highly responsive, efficient, and my ceiling / walls look like nothing ever happened in the first place. I even had a new light fixture arrive much later than expected and Alex worked with me to get someone out to quickly get it installed. Would certainly recommend GFM!

Alex and his crew worked on post leak repairs and upgrades to our home. He has a friendly, professional and full service crew that takes care of moving things, repairing, upgrading, etc.

Unlike other contractors who work with insurance companies, he did not put any pressure on us to sign up with him by asking us for money to provide a quote or sign some papers to represent us to the insurance company. He generously spent time with us to provide us with quotes, advice and support through the tough process of recovering from a leak. He also communicated with the Insurance company in a very professional manner.

His team did great work to project manage and complete the work on time. One area (sort of) that they could be better is the delicate and detailed finishing on paint jobs. Take this with a grain of salt, not being an expert in costing of such projects, you might find GFM to be a little expensive. So do your own due diligence there.

I would gladly work with him again if I ever have the need to do so.

Alex and team were a pleasure to work with. The team are very responsive, ontime. Professional and kind. I was lucky that "GFM" came highly recommended by a mutual contact which made my home repairs/updates hassel free and timely. I highly recommend Alex and team anyone looking for a contractor who deal with any water damage repairs, drywall repairs, remodeling, tile/counter top installation, floor work, plumbing, etc. Yes, I would rehire Alex and team should the need arise.

Alex and his crew were proficient & a good group of folks in general. We had a leak under our kitchen sink that turned into a complete remodel. Everything that needed to be fixed was done in a timely manner and done professionally especially when dealing with our insurance. They even went above and beyond and did extra repairs for us, including some sheet rock that had been previously damaged. You can feel comfortable in your decision to utilize their services.

My two bathrooms were heavily damaged due to a leaky pipe in the walls between them. I was introduced to Alex at GFM by my water mitigator who gave GFM very high marks in skill, timeliness, and customer relationships, and he was absolutely right! Alex and his crew (Alex and Sergei) took excellent care of my home, did lovely work, and were unfailingly responsive and kind to me, I actually enjoyed having them around! They hurried for me so I could return to normal life, and I'm very grateful. I am happy to recommend them without reservation!

Alex and his crew are without a doubt the most professional, contractor's I have ever worked with. Our kitchen had water damage and they not only did a brilliant job addressing all the damage, the flooring, tile, and appliances were much better than anything we could have found.on my own. Alex also helped me manage the insurance process. GREAT PEOPLE

Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
