I have had gutters, siding and doors installed. I like that when you get an estimate they go over your options in person and explain everything. Work done was great and if there are any concerns they stand behind their work.

Paige did an excellent presentation of the products that were to be used on our sun room. All of the workers are very professional and take pride in their work. Many things needed to be adjusted and tweaked, and everyone took the time to put the finishing touches on whatever they were working on. The crew worked like they were making it for them self. At the end of the day everything was cleaned up and put back in order. We will definitely think of Marshall Exteriors the next time we need something done to our house.

We were given the best options for our deck area by Anthony and he was very professional and honest. We had a beautiful fabric awning installed to cover our top tier deck. The communication through out the process with all the departments was easy and a pleasure. They met the deadline they promised us and it looks beautiful! Since my deck had full sun all day it was hard to enjoy especially with a baby! Now we can enjoy our deck comfortably and open or close the awning as needed. I’m very pleased ! I would highly recommend this company for any work you need!

Very pleased with new siding, gutters, shutters and Marvin windows. It's like having a new house. Honored to be the first install for Marshall Exteriors in Wayne County on the Marvin Integrity windows and patio door. The house is much quieter now from outside noise, warmer. I noticed right away that the sun was not as hot shining through my new windows. Highly recommend these windows and doors.

These guys did a whole roof on my Grandmother's house and garage. They did fantastic work! They were very respectable, put down tarps to prevent damaging her gardens, lawns etc. They even went around the house with a huge magnet to collect any nails that may have escaped. They completed this job ahead of schedule and the quality was above and beyond! Great job guys!

A leaky roof or damaged shingles are typically the most obvious signs of roof damage. A professional roofer can help identify the areas of your roof that need attention and determine the best plan of action. The roof on your house is very important. However, most people tend to ignore their roof until there is water leaking into their home and now it's a bigger problem. To avoid this, you should have your roof taken care of regularly. Your roof should be checked annually by a professional roofing contractor.


It's a major expense to replace an old roof with a new one. In addition to finding a good contractor who will complete your re-roof job for a reasonable price, you may need to decide whether or not you want the new roof to be the same type as the old. If you notice a leak, but most of the roof is still in good condition, it might make more sense just to repair the damaged spots. If you notice signs that the roof is wearing out and might require significant repair; or if your roof is more than 20 years old, you may want to consider replacing the roof.


A well-planned deck design can transform your yard into an area for relaxation and entertaining. A deck is also an affordable way to expand your living space.

We can install a ground-level, raised, or multi-level deck that compliments your landscaping and the style of your home. We offer a variety of materials to choose from, including wood and low-maintenance composite decking. We build decks using only the best quality products from leading manufacturers like TimberTech.
