Flooring business since 2002. Licensed,bonded and insured. Installation, sales, refinishing, repairs, stairs, stain, buffing, leveling, tile floors, shower, backsplashes. And much more. Professional and responsible crews.

"I am writing this review out of sheer gratitude and happiness! Juan and his crew truly went above and beyond on the existing highly glossy, aged yellow floors. They managed to convert them into a modern, extra matte , almost blonde finish without sanding, merely removing the polished surface and buffing out scratches and marks, creating a flawless, stunning finish! I’m struggling to find words to express my joy and a fraction of the cost of all other quotes AND the next day before Labor Day, so much more, important to finish with job complete in a few hours!!!! Please 🙏🏻"

"I hire Attic Insulation Labs to replace 6 air ducts, remove old insulation, rodent proof, air leak seal and sanitize my attic. They were so professional about everything they did that I already recommended them to two of my colleagues and they have already completed working on their attics as well. Their came in with a crew if 5 men, got to my house right on time, brought their professional attic cleaning equipment and were all nice and polite. Pastor, the foreman, gave me a brief of what they are about to do and vanished into my attic. A few hours later he showed me the clean attic, if was as clean as one would expect an old attic to be, and it didn't smell at all as bad as it did before the cleaning. A few more hours later and the attic was covered with a beautiful blanket of insulation batts. I can't be happier with their service, they really did a great job all around and deserve the good feedback."

Monteros Hardwood flooring has been a family owned and operated business for over 15 years. We take pride in the quality of each of our projects. We do all hardwood floor work for residential homes along with commercial projects. Monteros Hardwood flooring does the job right. FINANCING AVAILABLE - Please ask for details

"Javier made time to meet with me on July 4th for my estimate which was surprising but appreciated since I had limited availability due to living out of town. His knowledge about floor restorations was extensive and he answered every question I had about my 65 year old floor. He had even recommended a high traffic sealant since I am preparing my house for rent. Yes, I want the high traffic finish but I was concerned about the fumes for my tenants. He explained that they now use low VOCs and the smell goes away much quicker than the older stuff, which gave me peace of mind. I reviewed stain samples right then and we chose a slightly darker color stain to camouflage some of the nail damage from an old carpet installation. During the job, he worked with my project manager who told me his team was prompt, professional and delivered an absolutely beautiful floor. They even stained all of the thresholds including the entry so that it would match the floor! The last perk was being able to pay the deposit and final invoice from my computer at home. I highly recommend Monteros for your hardwood flooring needs. What a pleasant experience!!!"
