797 Bobby was absolutely wonderful and I highly recommend him! Other contractors quoted me crazy prices and tried to cut different holes in the door to accommodate keypad locks. Bobby and I had a couple email exchanges before he arrived where I sent him pictures of the locks I needed work done on...
Potomac Lock Service LLCColette was amazing and secured our 1928 doors back on and fixed the swing. I am going to have her back to fix my door knobs and old mortise locks.
Jeff is reliable, as the name states. He communicates well, shows up when promised, does EXCELLENT work, and tells you if someone else should tackle the task (Example, extended heights interior painting). Over the last year, he's installed a bath vanity, repaired and secured stair...
The guy was very professional installed locks. explained to me options I might have for security. For the work he completed I thought it was pretty expensive. Never followed up with me for estimate for key less entry.
Eastern Safe & Lock IncI 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...
General Home Improvement LLCLinda 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 had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"Had windows and doors installed by this company. The window installation went great. The bad news is that they do not seem competent at installing door hardware. My door has not latched properly since they made some unwanted modifications to the hardware (it worked perfectly before they started modifying it).have had them out three separate times to fix the issue they caused with the door latch and lock. Every “fix” they do seems to make the problem worse. I would steer clear of this company for door installations."

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.
