Went great. I had two exterior doors with different locks. Needed compatible locks for this to happen. Told which type of lock to get for one of the doors, so both could use the same key. Locksmith was very helpful and price was very good.
- Stella T.
They are a very good company. I found it very difficult to find a screen door company to install a screen door, but I found a very good company. They are a very good company. I would rate them at the top.
- Ed R.
Did not use them. Visited the showroom and was told that the product would be installed on top of the patio door framework that we had, rather than completely remove the old pation door
- Matthew P.
Majestec Premium Security Screens just finished my door installs. I got the front and back door done. Front door had a sidelight that I also had covered. I must say I am very impressed and glad I waited for these doors... they look AMAZING. They were custom made. I had the door handle moved...
- Leticia S.
Updated this today, still quite happy with my front door!
- Barbara B.
Since it was such a small job, price quoted over phone was minimum charge for service call. Set appt. time within a 2-hour window and the two reps arrived during the set time. One measured the window frame and went out to the truck and made a new frame & screen while the other person worked...
- Roger U.
The company subcontracted the work out to a handyman. He and his helper arrived with the doors. They removed the old doors and checked out the openings to see if anything else needed to be done before the installation. They found that some moulding was not installed properly. They moved...

"Our small house, built in 1948, is excellently located, but all of the windows were outdated louver windows, which were drafty, allowed external noise to enter, and caused our heating and cooling to escape. We had wanted to replace them for years; however, previous quotes from other companies were well beyond what we could afford. We decided to try again this year and requested a quote from Smart Window Company. David Winkler promptly contacted us on January 18, 2025, and arranged a Virtual Consultation via Zoom for the following day as this was most convenient for us. During the meeting, he spent nearly two hours understanding our specific requirements and exploring available options, providing a detailed explanation regarding the custom replacement windows. He demonstrated professionalism and was approachable throughout the interaction. On January 20, we received our initial quote for replacing 11 windows with 10 new ones, as we opted to merge two old windows into a larger picture window in the master bedroom. All windows included a lifetime guarantee. Although another company provided a significantly lower quote without any guarantee, David diligently worked to adjust the price until it was comparable to the lower quote. Consequently, we signed the contract with Smart Window Company on January 28. The Installation Manager, Tom, visited on February 3 to verify the final measurements for the windows. He professionally explained the installation process and advised us on preparations. On February 8, he informed us via email that our project had been ordered, with delivery expected in 6 to 8 weeks. The windows arrived ahead of schedule, and we scheduled the installation for March 3. On the installation day, the three-man crew led by Bryan, the Crew Leader, arrived promptly at the appointment time. Bryan communicated effortlessly in perfect English with us, and in Spanish with Byron and the rest of the crew. He remeasured everything and verified each window's size. Unfortunately, one window had incorrect dimensions due to a manufacturing error. Nevertheless, the team proceeded efficiently and meticulously, removing the old louvers and installing the replacements within four hours. Bryan assured us that the correct-sized window would be expedited from the manufacturer. The job site was left clean and tidy both inside and outside. Today, on March 19, Peter, the Job Foreman, installed the remaining window, completing the task in less than an hour. We are extremely satisfied with the fantastic customer service, the excellent quality of the product and the workmanship and the overall dedication to customer satisfaction provided by the entire staff at Smart Window Company. We highly recommend them to anyone in need of quality windows at a reasonable price."

FAQs for security door installation projects in Torrance, CA
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.
