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!!!"

"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Insulation installs or upgrades FAQs
R-value measures how well insulation resists heat flow, which directly affects your home's energy efficiency. The higher the R-value, the better the insulation. By calculating the R-value needed for your specific climate and home design, you can choose the right insulation materials and thickness to keep your home comfortable and reduce heating and cooling costs.
You don't need to remove your old insulation before adding new insulation, as long as it's in good condition. Adding new insulation over existing materials can improve your home's energy efficiency. For example, you can install blown-in insulation around fiberglass batts or place rigid insulation over existing layers to enhance the overall R-value. However, if your current insulation is wet, moldy, or damaged, you should remove it to avoid health risks and maintain optimal performance.
Installing insulation typically takes five to twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the type of material and your home's layout. If you need to remove old insulation, have a larger home, or hard-to-reach areas, the project may take longer.
The International Association of Certified Home Inspectors has said foam board insulation can last up to 100 years if properly installed. Some insulation materials can suffer from water damage or start to sag over many years, thus reducing their insulating ability. Foam boards shouldn't suffer from sagging but have the potential to get damaged. Any broken pieces of foam board can reduce its insulating effectiveness.
