“In June, we had all the windows in our house installed. Our previous windows were at least 30 years old and were in poor shape. Of the three quotes we received, Milcon Design & Build was the most straightforward and to the point, the best value, and had the earliest install date. Everyone was fast, efficient, and very friendly on the install date.

The windows were installed without a hitch, and my husband and I were amazed at the difference—the decrease in sound, the quality of the windows—we had to turn up the air because the house got so cold. After all, the cold air was actually staying in the house! We couldn’t be happier. We would definitely recommend Milcon to anyone and plan to use them again in the future.”

– Kimberly M.

“We are very pleased with Milcon’s work to install our basement sliding door. They were very professional, prompt, and responsive to our questions. I highly recommend them for all the services you may need. They were also the most reasonably priced of all the companies I contacted. Highly recommend!!”

– Meagan F.

“We worked with Milcon Design & Build for our home renovation and couldn’t be happier. They did everything they said they would do down to the last detail. The crews were on time and acted like a well-oiled machine, always mindful of us and our property. Will definitely be using these guys again.”

– John M.

Q: How Do I Know My Windows Need Replacing?

A: When your windows need to be replaced, there are several signs that you may notice. These include:

  • Feeling drafts around the windows
  • Windows will not open or close properly
  • Locks are no longer working on windows

Of course, age can also play a massive role in whether your windows need to be replaced. If your windows are over twenty years old, a replacement could make a huge difference in your home.

My Current Patio Doors Is Always
Cold In The Winter, What Can I Do?

A: A common issue many people have with their patio doors is how cold they are in the winter. Old, outdated patio doors can let in cold air that makes your home miserable. Replacing it with a more modern and energy-efficient patio door is your best option.

Q: Should My New Trim Match My Siding?

A: Most people opt to go with trim work that does not precisely match the siding but complements the siding. It helps to make a visual splash and up your curb appeal when choosing a different color than the siding.

Q: What Is The Most Secure Material For An Entry Door?

A: We suggest you use fiberglass or steel entry doors with security in mind. Luckily, we offer both options.

Q: My Roof Has Missing Shingles, Does It Need Replacing?

A: Missing shingles can be a huge sign that your roof is nearing the end of its life and needs to be replaced. Once we see the roof, we can let you know whether replacing the roof or just repairing the missing shingles is the best idea.
