We are a family and veteran owned and operated business located in Littleton CO. We are your true one-stop concrete, retaining wall, fencing, deck/pergola company. We offer many other services as well. Call Gabriel today for your free consultation at 303.994.2944.

"The work was completed in a timely manor and overall looks good, during the project Gabe tried to change the scope many times, but ultimately did stick to our quote. Once work was completed he requested an additional $600 “because we did such a good job” finally within 90 days of having our fence and gate installed the gate began to sag. I contacted Gabe to give him an opportunity to make it right but he did not respond in any capacity. Moral of the story: make sure the work is 1000% because once peppers leaves they won’t return to fix any errors."

We’re the best gutter maintenance guys in town, and our customers say so. We repair, replace and clean gutters. Let’s connect.

"The project went very well. When dealing with anyone for a project, you need to make certain that there is a clear understanding of what work needs to be done. While a good proposal and estimate was given to me for the work, I found that my definition of a specific type of work to be done (i.e. with French drains), was not the same as that of the company. This was my fault, since I should have better understood what exactly was going to be done. Also, if the gutters have not been cleaned and maintained in a while (out of site, out of mind), as mine were, be prepared for some extensive and expensive work to be done. My take-away lesson from this project is that I will have my gutters cleaned and checked more often, probably in the Fall. Otherwise getting this type of work done is expensive. And if water is falling near your foundation, it can quickly get very expensive. Vito was responsive, though sometimes a bit hard to reach, and the crew he sent was punctual and appear to have done a very good job. (I can't climb up on the roof to personally check the work at my age.) I would recommend Gutter Maintenance Pro, and I plan to use them again in the future to check my gutters on a yearly basis with the right cost considerations."

"Greg was absolutely great----arrived early, incredibly professional, and found several things I suspect a lot of other competitors would have missed which were very much appreciated. The inspection went fast, but nothing was missed. This guy obviously knows his stuff, and we've already recommended him to a neighbor considering selling and buying a new house too. Again, great guy, highly professional and knowledgeable, and reasonably priced. A+++ Scott Hoffman"

Gutter Repair and Replacement questions, answered by experts

The trick to getting gleaming gutters can vary based on the material of your gutters. Aluminum gutters can often be restored to pristine condition by using a cloth to scrub them with a solution consisting of 1 cup of vinegar and 1 cup of water. Vinyl gutters can be whitened using dish soap and water. For deeply stained vinyl gutters, adding bleach with water and dish soap may help to remove black streaks. Many retailers sell premixed gutter sprays. Applying cleaning solutions to dry gutters before rinsing can help cleaners attach to dirt and grime for easier removal.

Yes, caulking or sealing your vinyl gutters is a good way to help prevent gutter leaks. When you’re installing gutters, it’s important to overlap the sections to help avoid issues like leaks or drips, but they can still happen. In this case, adding caulk can help. Make sure to use a caulk designed for multiple surfaces, like a silicone-based caulk. You can also purchase a gutter sealant as well, which is specifically designed for this purpose.

Poor gutter drainage can cause sagging gutters, roof damage, mold, mildew, rot, basement flooding, and foundation cracks. With gutter replacement costs possible for just $500, getting the right system can save you thousands in repairs down the road.

If you don't want to install gutter guards, the most inexpensive alternative is to clean your gutters as soon as they start to fill up. You can use a leaf blower attachment to make this process easier. You can also install gutter screens, which are typically made of wire mesh, nylon, or foam. These usually cost much less than a full gutter guard installation and can reduce regular gutter cleanings.

The best way to seal gutters is with a combination of waterproof roofing cement and silicone gutter sealant. This powerful duo works to prevent water from escaping through holes and cracks while allowing for breathability. While you can use polyurethane sealants, silicone sealants tend to be more flexible when it comes to climate. Silicone is UV-resistant and bonds well to many surfaces. However, polyurethane sealant bonds better with wood.
