Guys With SqueegeesI have been looking at security doors for 3 years. Most of them look the same but prices were varied and you sometimes did not know who would install. I finally decided to purchase so I went to the Denver Home Show in January or February. I talked with a couple of security door dealers but I...
SECURE-ALL COMPANY INCRekeyed 3 security doors and several extra keys and replaced the lock mechanism between house and garage. They came the same morning I called, and were quite professional. i will definitely use them again.
The doors are fantastic quality and not cheap. The doors are custom made and of superior quality. You do have to wait for their manufacture, and there is significant installment modification to render the doorway secure. Oveall we are very statisfied.

"I had siding replaced and very displeased with the entire process. The crew did a poor job for what I paid and have already had to be back out here 3 times in a month to fix their mistakes. Crew cheif never checked the work to determine if the quality was up to the company standard. The crew left the property a mess with my belongings scattered around the yard. They had leftover pieces scattered as well. The craftsmanship and quality was aubpar for the price. No care for the property. Damaged driveway, roof, windows, and garden bed. Chalking already cracking. Large gaps in the siding. Siding already buckeling. Seams not together. Asked to speak to a manager or supervisor multiple times and still no response. I was promised certain tasks at point of sale that company will not follow up on. Over all this company treats their customers as money and gets in and out with little oversight or quality check. I am very displeased with the product I got for the money I paid. Will never recommend."

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.
