"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"We were VERY happy with Don's performance and plan to hire him again for work in one of our bathrooms.   He was on time, professional, and very knowledgeable about many areas of home remodeling and repairs.   In addition to his friendly demeanor,   he also gave us some great suggestions to save us some money.   He worked non-stop for the time that was agreed to via the Angie's List Coupon.     Across the board,  a GREAT experience!"

"James and his team did a good job on renovating our whole house. Before choosing James, we compared a few companies. We made our mind to use his team because he made us feel comfortable to work with. We are 1st time home-owner so finding a contractor who has the patience for us and the knowledge to walk us through decisions when buying materials are very important. James is the one met our requirement. We have 5 bedrooms 2 baths. It took about two months and half to finish because certain materials we ordered did not arrive on time. During the renovation, there were unexpected issues that James discovered, but he was always able to figure out a solution that falls into our budget. I would recommend them to my friends who are in need of a contractor. Oh, BTW, I like the music turned on when they were doing the work. A few cool guys to work with, and they made the stressful renovation project a little more enjoyable."

"Prompt, reliable, and professional service. Good communication with Steve via email and Dennis on site before, during, and after the project was completed. Fair price for the job and good workmanship. I have already recommended them to others. I had them replace the railing, treads, and bottom platform of an outdoor staircase leading up to a second story deck."

I’m a reliable construction and maintenance professional with hands-on experience in residential repairs and renovations. I currently work as a maintenance technician for a large property, handling everything from small fixes like lighting and fixtures to larger projects such as laminate flooring, sinks, and vanities.\n\nPreviously, I was a project manager overseeing full kitchen and bathroom gut renovations, while also working hands-on from demo to installation. This gave me a strong understanding of doing jobs efficiently and to a high standard.\n\nI take pride in being detail-oriented and delivering quality results that last. I’m also honest and upfront—if something is outside my expertise, I’ll communicate that clearly. With strong customer service skills, I focus on making every job smooth, professional, and stress-free for the customer. \n\nIf you’re looking for someone reliable, hardworking, and committed to quality, I’m here to help get the job done right.\n\n

Locksmiths questions, answered by experts

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

If your door handle turns without opening, the most likely culprit is a loose or stripped spindle. This part connects the handles to the latch mechanism, and when it’s not properly engaged, turning the handle does nothing. Other issues might include a broken latch, loose screws, or even something small blocking an inner mechanism. In any case, it’s usually a matter of tightening, adjusting, or replacing a worn-out part inside the handle assembly—or calling in a professional to do it for you.

The cost-effectiveness of fixing or replacing a door lock depends on the severity of the issue. Repairing a minor problem, such as loose screws or a need for lubrication, is usually cheaper than replacing the entire lock. However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment. New locks often have improved security features, enhancing your property's safety.
