Larry was fantastic! Not only is he a genuinely wonderful person, but he is a perfectionist and master of his trade. He prepped and drywalled over the failing plaster walls in 2 of my closets that had been damaged due to water. Both closets were fairly difficult to work with, and to work...

These guys are great. My garage door was broken and ended up needing to be replaced entirely. Other companies I called didn't call me back or had long wait times, where these guys came out the next day. John was really nice, worked quickly and explained everything in and way I understood. He...

Fine, except the garage door opener didn't work after a few days because it had an old battery. It took a second service call to replace the garage door opener with one that worked. They gave me a second opener for free because of this.

I wish every subcontractor we are using to renovate our townhome was this good. The window and door package is one of the highest dollar amount we are spending with any one company, so it has been extremely reassuring to be feel that we are in such good hands. David handled everything with...

Good overall - Joyce was VERY helpful on the phone in advance with advice on what I needed to purchase and what to look out for (before she even knew if I was going to hire her). Arrived as scheduled. Very personable. Everything went well with a couple exceptions...we purchased a handle set...

FAQs for security door installation projects in Litchfield, CT
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.
