I'm happy to see the job done at my house. We are enjoying our beautiful patio and front yard. Now our house is looking beautiful. Thank you to Wilmer Construction and his team for providing us this satisfaction.
Five stars all the way. We had our entire house painted and the quality of work was outstanding. The quote was very reasonable, the crew worked around the clock to get the job done, and they were honest, trustworthy, and very detail oriented throughout the whole process. We are very happy with the result and highly recommend them.
Wilmer did a great job for us! He removed and replaced all of our ceiling drywall after a massive tree demolished our house. He takes pride in his work and delivers professional results.
Wilmer and his team did such an amazing job when subcontracted for the tile in my new primary bathroom that I knew immediately I wanted to hire him to install new flooring after a water main break on the first level of my house.
