An effective gutter system will protect your roof and the rest of your home from flooding and other water damage, whereas faulty gutters can contribute to problems such as rot, mold, decay, a leaky foundation, cracks in the roof, and a flooded basement. Old gutters can become worn out and develop leaks, which will cause a number of problems for your home. Look for the signs that you might need a gutter replacement and contact our professionals as soon as possible so we can assist you quickly and resolve the issue before it worsens. You want to keep your gutters updated and effective so they can continue to protect and preserve your home. Also, look into the incredible gutter covers Mainstream Home Improvement provides to further the quality of your Davenport, IA home’s gutter system.

Gutter Covers
Davenport, Iowa

No homeowner enjoys cleaning gutters. Call Mainstream Home Improvement in Davenport, IA to inquire about our GutterRoof and GutterRx™ products and eliminate the need to climb dangerous ladders and clean out unwelcome debris and pests from your gutters. The concept of the GutterRoof and GutterRx™ gutter covers is simple: they are designed to protect your gutters. Debris will fall on your gutter cover and then blow away in the wind, so you’ll never have to get your hands dirty again. GutterRx™ offers a sturdy, perforated aluminum cover that also implements a rough surface to help the water flow at a slower rate, which allows the gutters to handle more. With GutterRoof, we can match the color of your shingles to have an attractive look that is also long-lasting. Say goodbye to this chore forever!

Roofing Replacement
Davenport, Iowa

When you need a roofing replacement, we will follow the same process as our regular installations. Most importantly, we want to remove all of the old material before replacing your roof so we can ensure a solid and healthy foundation. Your roof is an important and invaluable part of your house—it serves as your first defense against Mother Nature’s elements and helps to maintain your home’s structure, function, and beauty. Depending on what kind of material was used to build your roof, you may need to replace it every 15-20 years. On the other hand, if you’ve sustained damage to your roof through a storm or accident, our experts at Mainstream Home Improvement in Davenport, IA can assist you immediately to restore the integrity of your roof and your home.

When you invest in new siding for your home, you can give it a completely updated look, while decreasing your energy bills. At Mainstream Home Improvement in Davenport, IA, we use 25-foot siding panels, which will give you fewer gaps, less line breaks, and show off the beauty of your home’s exterior. If you invest in our quality materials, you will save money in the long run because gaps and dents will expose your home to pest infestation and water damage. Our quality siding is built to last. We proudly install Alside® Vinyl Siding, which promises to never split, dent, crack, splinter, or blow off your roof. Alside® provides not only appeal but also greater durability as well as a wide range of design options and colors that won’t fade. Your siding will look immaculate for years to come.

There are many factors to consider when consulting on home improvement services. We know you have questions, so save yourself time and look through some of the most common concerns and inquiries our customers have had and see if you can find the answers you’re looking for. If not, feel free to contact our experts with your specific questions, and we’ll give you thorough responses, tailored to your unique situation.

What are some of the most common pricing games that typical window places want to play?

Some home improvement contractors in Davenport, IA are afraid that you will turn them down, and so they give you a bottom-of-the-barrel quote just to try and get you to say “Yes, I’ll take it.” They assume you can’t afford what you really want (which is usually not true) and that you want to settle for cheap windows and fewer features for a lower price. Always make sure you make a home improvement decision based on what’s included rather than just a price.

You guys have a lot of glowing reviews. Why can’t I find customer reviews on other companies’ websites?

We’d like to think that it’s because we’re just nice people, but obviously, there are a lot of nice contractors out there. There are key differences between our services and the actual product we provide. Our window installation process is completely different than your typical window installation in Davenport, Iowa. We try and put forth the same kind of effort on siding and roofing. Our office manager calls you DURING the installation to make sure that all your questions are answered, and that you are happy with the work we do.

Why do you only have production managers or owners on the final walk through?

Homeowners love to walk through and see the before and after results. The difference is so dramatic, that we like to call our final walk through the Victory Lap. However, while we do all we can to have a flawless installation every time, once in a while we catch something that we can do better. Most homeowners would never know the difference, but we use this final walk-through as our quality assurance check. We guarantee our windows for life, so it only makes sense to do them right, so we never have an avoidable issue.
