I am not tickled that I agreed have him shave and sand parts of the door down because the security gate knob scrapped the wooden door. The security door and transom provide a better seal from the elements though the aesthetics are not optimum. Paul did a great job with clean up and could...

I wanted the locksmith to swap out locks on my front and back door. The back door was no problem but he struggled for over three hours on the front door bolt lock - taking off the lock, putting a new one on that stuck and didn't lock well and then re-placing the new lock with the old, which...

Linda was incredibly patient as we went through multiple designs of the two sheds. The sheds ultimately came with multiple windows, overhead lights, wall power outlets, security bars, solid cedar doors with Schlage lock systems, and entry ramps. They were customized to a great degree,...

Bini was absolutely fantastic to deal with -- I called him on a Monday, and he went by my house that same day to prepare an esimate. By Wednesday my new security gate was fabricated and installed on the front door. Bini was very responsive to my calls and emails. I would definitely...

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price.

We understand the importance of making the right decision without headache or high pressure. That's why more customers refer us to their friends and family than any other window and siding company. Not surprising when dealing with professionals that care about their customers and love what they do. ---- We thank you for visiting our profile and look forward to improving the quality, enjoyment and energy efficiency of your home. ---- Additional phone - (703) 462-6100. Additional fax - (877) 867-3726. Award winning. Additional DBA - Vinyl Technologies Energy Service. Additional contact name- Brian Weil. Additional email - [email protected].
"We hired Unicorp to replace all our windows, doors, and siding—and the result has been an amazing transformation of the entire house. Not only was the work done to perfection, but the people we dealt with at every stage made the whole experience a pleasure. From the start, our sales rep Alex was informative and responsive, answering all our questions over several weeks—so that by the time we signed the contract, we were totally comfortable with the project design, and knew what to expect when work began. Paul was in charge of the window and door installation. He and his crew finished all the work in just two days, and kept the work areas clean as well. Everyone was friendly and courteous, and Paul himself was an unforgettable character. Window replacement can be an overwhelming job, since it involves every room in the house, but Paul made it fun with entertaining conversation. And he was an artist with the trim capping, making sure to match the style of our colonial house so that the windows would have definition instead of appearing flat. The windows and doors themselves are top-of-the-line quality. They instantly modernized the house, and because of the improved energy efficiency, our AC is able to maintain the house temperature so much better in the blazing hot summer. JR was in charge of the siding job and other finishing touches. His crew, Nam and Augustine, were incredibly talented and hardworking (even after driving four hours to our house each morning)! They completed the siding on our addition in just one day. The end result is stunning, and the insulated vinyl siding has made the addition much quieter and more comfortable. JR came up with creative solutions, like figuring out how to design the columns and header so that they’d fit in the tight spaces around our door. And he was always easy to reach by phone or text. There were a few issues with the materials delivered for the shutters and the door surround, which caused some delays toward the very end of the project. But JR was committed to making everything perfect, and he came back himself to do the final installation and painting. This was the largest renovation project we’ve ever undertaken, and Unicorp made it such a positive experience. We couldn’t be happier with our “new” house, and we look forward to calling them again, when it’s time for us to get a new roof!"

FAQs for security door installation projects in Garrett Park, MD
The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month
Smart home locks: $150
Smart home lighting: $15–$90
Smart smoke, fire, and carbon monoxide alarms: $35–$100
Smart thermostat: $130–$500
Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.
The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.
Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
