What was great was that he had hundreds of pictures of the iron work they've done on his iPad, and it was so nice to see samples and talk through what I wanted, and he'd show an example of the work on his iPad. there was no second guessing. he said that the work would be done on Sat. however, one of his guys called in sick & the work couldn't be done. He promised me that even though they didn't work on Sundays, he said that he would be there to install the bars. And on Sunday, he and his crew were there. T is the utmost professional, courteous, on time and within budget. plan to use him again to install a two more safety rails and a handrail in a couple months.

"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."

"We were looking to increase our attic insulation and met The Home Doctor Company at the Capital Remodel and Garden Show in February 2025 as well as some other companies. We consulted with several companies and decided to go with The Hone Doctor for our attic insulation. The company rep, Chris Lear, was very good explaining what they would do and why our attic needed R-38 insulation. I knew we needed more but did not realize our attic was only R-13. I have worked with numerous contractors before on projects and felt this was a really good company plus they have great reviews. The installation of the attic insulation went very well. They do install siding as well but decided to put this project off for now. Would highly recommend this company."

FAQs for security door installation projects in Largo, 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 an80-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.
