They are super responsive, stick to the timeline and stand behind their work. They were clear and set expectations well. The teams that came and did the work were respectful and friendly. They did not talk over my head and make me feel silly or dumb for asking questions. They kept the worksite clean and safe. > > The work was amazing. I have received so many compliments. I will use them again without a doubt! **★★★★★ — HU-806274891, March 2024** > There aren’t enough superlatives to describe the immense satisfaction we feel with the quality of service and workmanship delivered by QPS inc. Led by their CEO, Alfredo Henriquez, the entire team is extremely professional, respectful and knowledgeable. They’re simply brilliant at what they do - experts in their field and above all else, really wonderful people! If you want a contractor that truly takes pride in all that they do and offers fair pricing, look no further than QPS Inc.. We trust them completely and will only ever use them for any future projects, and will always recommend them to others! > > QPS Inc. was referred to us as we were struggling to find a contractor that gave us confidence that they could handle our project. Our project was to reinvigorate and modernize our first home, which we’d just bought. This home is over 100 yrs old and we wanted to ensure that the work only added to its beautiful historical charm. > > We had identified several things that we wanted to do to our home. See list below. > OUTSIDE: > \- reinforce the foundational structure of our detached garage. > \- rebuilt the Juliette balcony floor, improved it’s drainage system, and installed custom metal railings to modern code standards. > \- rebuilt the wooden hand rail for the outside staircase to modern code standards and painted as if original. > \- rebuilt brick front porch steps to even out the step heights and bring to modern code standards > \- had custom curved metal railings fabricated and installed on front steps. > \- installed gutter guards on all roof gutters. > \- installed new chimney caps. > \- home is a Georgian style with red face brick on the outside with wooden trim. QPS repointed and regrouted all the face bricks with bright white lime stone. This was a lot of work, but it looks incredible - get so many compliments! > \- painted all wooden trim on the exterior. > \- installed French drains to improve the drainage in the front of the home. > \- installed gas lines outside for BBQ and fire pit. > \- reinstalled and fixed the landscaping irrigation system. > > INSIDE: > \- replaced entire HVAC and air duct system throughout the home. Added an additional vent to the master bedroom and added another return to improve the efficiency of the system. Installed smart thermostat controller for system. > \- new air ducts required larger space to run in the walls and QPS made them wider without affecting any of the detailed historical trim thereon - magicians!! > \- opened up a wall between the kitchen and breakfast nook and made it look as if it was always like that. > \- redid the powder bathroom and installed new toilets in all the bathrooms. > \- built two new closets in the master bedroom to replicate the existing ones on the other side of the room to create a “his & hers” set of closets. > \- built shelving into all the closets in the bedrooms to modernize them. > \- replaced all the insulation in the ceiling. > \- built a beautiful fully finished & permitted laundry, and gym in the basement. > \- plus MORE… **★★★★★ — HU-202692583, July 2023** > QPS, Inc. is one of the most, if not the most, professional and detail-oriented group I have worked with.

We have done business with more than 140 other general contractors and other construction companies, both locally and throughout the state of California. > > Without question, we find QPS to be one of the top three general contractors that we have ever worked with. > > They are attentive, dependable and a pleasure to work with. They always do what they say they’re going to do but even more than that they under promise and over deliver every single time on every single project. Their prices are more than fair and they never overcharge….. it’s run like a family business is supposed to be operated. There are never excuses. > > QPS has a significant staff of qualified professionals. They never take on more work than they can handle or work that they are not qualified for. > > > To be honest, we are always looking for projects to do so that we can partner our clients with them. > > We , ourselves are an interior design and interior architectural firm, who represent quality workmanship as you will see on our website, www.warrensheetsdesign.com. > > When asked to give recommendation I the president of Warren Sheets Design, jumped at the opportunity to give my two cents about QPS. But since I have been asked, I’m giving more than two. Cents to whoever asks! > > I am all in to recommend QPS to anyone who is looking for a general contractor to do a quality job for them that is small or large. > > QPS is an extremely credible firm.
