"The installation of our new garage door went perfectly. The team worked efficiently, cleaned up after themselves, and made sure everything looked great. They even showed me how to use the remote properly."

"I want to give my highest possible recommendation for Craig at Mel Martin Windows! I hired them when I found significant rot and decay in the wood around my front door. Craig came to our home, evaluated the situation and created a great plan to fix everything. We ended up replacing the wood around the door and installing an entirely new door. Craig did an exceptional job at recreating the decorative brick mold we had on the door frame by using PVC products. He corrected all the previous issues and now gave us a new solution that will withstand the weather for years to come. Extremely happy with his professionalism, punctuality, flexibility and pricing. He is a true craftsman and a pleasure to do business with. Very pleased with how our project turned out."

"Signed contract on May 8 for deck build.On May 12 rep came to my office to collect deposit of apprx $13,000. He said project team meeting on Wed & would update me then on start date etc. On Fri May 16 I had to reach out to him. He wrote the team had met & materials were ordered. An hour later he wrote back that he was misinformed & that his boss was going to call me next week. Despite this, dep check cashed. On Mon 5. 20 rep wrote back that they had forgotten certain costs & to proceed it would be $8,000 more. Not a typo. $8,000 more. No apology. Ridiculous, contract rescinded. I wrote that he could return my deposit at my office just as he had collected it. On Wednesday the 21st I got a text from "Tom," presumably the owner/boss, saying he would "drop a check in the mail" to my address. Today is May 30th, Friday, and still no check. Check at a minimum should have been overnighted. They owe me interest not to mention the deposit to hire a contractor who will honor contract. Bad."

"Morgan Exteriors went above and beyond!! Their professionalism and expertise from the first initial call to Josh, on site estimate by Lou to the final measurements and all questions and concerns answered by the install Manager PJ. We had questionable weather and the two installers were running a little late. They arrived at 11:30 AM and had all seventeen windows installed by 4:45 PM! These two gentlemen were are very experienced and have many years under their belts and they are employed by Morgan Exteriors and have been for many years, it showed. That consistency, workmanship and professionalism completely convinced me of Morgan Exteriors warranty not just on the windows but the workmanship of the install. This took the fear of some of these other window installer businesses away completely. What I didn?t want is a company who installed a certain brand of window and that company hired inexperienced contractors not to be heard from again. The final project came out spectacular!!!!"

Window Door Contractors questions, answered by experts

A front door lasts between 20 and 100 years, or an average of 30 years. How long it lasts depends on the type of material, the environment, and how well you maintain it. A door with coverage over it will last longer than one exposed to the elements. Using high-quality paint or sealants can also help extend the life of your front door. Wood front doors tend to have shorter lifespans than other materials.

Wood is by no means the only type of front door material on the market. You can also choose from several other options, including:

  • Aluminum: Low-maintenance and affordable, but lacks insulation 

  • Fiberglass: Offers excellent insulation and durability for a decent price 

  • Glass: Offers beauty but less security or insulation, and a higher price tag 

  • Steel: One of the most economical options if you’re looking for affordability, low maintenance, high security levels, and a door that will last

  • Wrought iron: Attractive and secure, but costly and heavy 

You should hire a licensed and insured door contractor with prior experience installing folding doors. Installing these doors is much more complex than installing a standard sliding door; don’t leave this work to a general handyperson or attempt to install it yourself.

You should generally cut between 1/8-inch and 1 inch when planing a door. If you cut off more than that, you risk damaging the door. Planing too much from the bottom of your door can cause noticeable gaps, so it’s always better to start with as thin of a section as possible and work in thin layers until your door no longer sticks.

Sliding doors and pocket doors are both great space savers, but they work a bit differently. A sliding door moves along a track and is always visible, sliding next to a wall or another door. On the other hand, a pocket door slides into a slot in the wall, hiding away completely when it's open. This makes pocket doors a perfect choice if you're looking to maximize every inch of floor space, unlike sliding doors that can still take up some room even when they're open.
