Abrahamson Services provides a wide range of services to the 4 county Milwaukee area. Anything from windows, doors, roofs, gutters/toppers/cleaning, to roof raking, ice removal and interior work

"Ken was fantastic from start to finish. I hired him to remove an old basketball hoop, pour new cement, and install a new one. The job turned out to be much tougher than expected—the old cement was nearly impossible to break up and the clay ground was hard to dig deeper for the required dept —but Ken handled it like a pro, using a jackhammer and digging through hard clay soil without complaint. Despite the extra work and materials needed, he stuck to his original price even when I asked to pay him more, which speaks volumes about his integrity. He returned a few days later to assemble the hoop, and the final result was perfect—every measurement was spot-on. Ken went above and beyond, and I wouldn’t hesitate to hire him again. Highly recommended!"

Home Security Systems questions, answered by experts

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

In general, keyless door locks are considered safe. They can’t be picked like a traditional lock, and unless a thief can guess your code, it’s pretty tricky to break into a house with a keyless door lock. But that doesn’t mean they come without risk. 

When asking yourself, "Are keyless door locks safe?” consider the style of the system. Hackers could potentially break in if it operates on Wi-Fi, but it’d take some time and effort. You’re also at risk for a power outage, depending on the type of lock. That being said, there are no more risks associated with keyless door locks than a traditional lock.

Each has its use, depending on the scenario. Security doors are primarily intended to keep people out of the home, while storm doors are used to protect the home from extreme weather. Both tend to be made from heavy-duty metal and may include glass panels to allow light to enter the home. Storm doors can feature mesh screens, just like screen doors, to allow for increased ventilation and to keep out pests. Security doors rarely, if ever, have mesh screens.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

Various types of deadbolts are available, from the classic single-cylinder lock to a double-cylinder, rim deadbolt, smart deadbolt, and electronic deadbolt lock. Most homes in the U.S. use a single-cylinder deadbolt lock, which requires a key on the exterior and only a thumb turn on the interior to open or close the lock.
