What Our Customers Say

Ive known Paul and his guys for Years. What makes Paul standout is the genuine care and concern he and his team have for their customers and their homes. There isnt a company I would call before I called Paul first in any situation.
Scott Storms, Google Review

Highly Recommended!!.. Paul and his team of contractors are awesome. Paul is such a nice person, professional business man and great at his craft. Paul completed multiple upgrades in my home recently. Though not very big jobs, he treated us with respect and care for the work he completed. Paul kept up notified of any scheduling changes and conflicts so we could work around them and get the work completed. His dry wall and electrical team were amazing and found solutions to our outdated electrical and ceiling fan issues. We truly appreciate Paul’s efforts. If you are looking for top notch work from an amazing, trust worthy and nice organization, then seek out Paul and his team!!.. Curtis & Sandra

I hired them for new floors and gutting 2 bathrooms. We ended up scraping the popcorn off the ceilings, putting in can lights, taking down a wall and getting a beautiful handmade island, and they wrapped my beam.

The quality of work was outstanding. Paul’s attention to detail (like wrapping the beam and putting in a floor outlet for our couch) was impressive. His crew were on time, respectful and a joy to have around. I will hands down only use Paul…

Paul’s company was very professional in doing my roof R and R job. They did exactly what they said they were going to do and for exactly the price and the amount of time for the job. I recommend them for any job because Paul is very knowledgable about construction.

Angel Ramirez, Google Review
The company had to remodel a bathroom after extensive plumbing work. Drywall, paint and placing fixtures back in place. Quality work, every thing was perfect. Also had a major repair on my patio overhang. Mostly dry rot and worn runners. They replaced all faulty lumber and completely painted all wood. Fantastic craftsmanship. Each project was completed within my budget and to my satisfaction. Crews very competent, on time, and cleaned up areas each day. Very professional.
