Cornerstone Services - Electrical, Plumbing, Heat/Cool, Handyman, Cleaning

I had Erin & Nilda come do a whole house deep clean today for the first time. They did an amazing job. They left no stone unturned. The house smells and looks so fresh and clean. I loved their attention to details, too. I felt comfortable having them clean while I was out of the home! Thank you for this whole house refresh before I head back to work as a teacher! ♥️

Jorge, Ashley & Arnold all sis an awesome job!
We wouldn't hesitate to ask them to come back to qork on other projects here.

Cornerstone Services and specifically the "Handyman" team lead by Alexander Rivera preformed meticulous and wonderous work.
They transformed my back deck from a dilapidated, sad deck to a magnificent, gorgeous show piece.
The team was on-time, courteous, friendly, professional and proficient. I would not hesitate to recommend them to anyone who needs any "Handyman" services. They also fixed my garage door and the flashing on my roof.
They can do it all and do it all well.

Josh did a perfect job and finished ahead of time. He was polite and efficient and he was excellent with my little tomcat who can be difficult.

Gregg was positive, professional and shared knowledge willingly.
As he was here less than an hour..any chance for a discount on diagnosis fee?
TY for your kind consideration. Said discount would encourage me to use influence for future recommendations of your services.
Blessings of Appreciation,

I had a great experience working with Tom for my electrical service. He was thorough, paid close attention to detail, and took the time to walk me through everything. I truly appreciated his expertise and the care he put into his work. Tom made sure all of my questions were answered and worked with me to ensure we covered everything that was needed. Highly recommend!

Erin and Nilda I’ve been cleaning our house for a little over three years and they have always been extremely reliable and done an incredible job and I’m usually home when they’re home and they are always very nice to me and my dog. I would highly recommend both of them to any of my friends.

We’ve been using Cornerstone’s cleaning department for a couple of years now and they’ve been consistently excellent. Erin and Nilda are professional, kind, and reliable. They always leave our home sparkling clean and add thoughtful touches like folding towels and blankets into fun shapes (cute photo attached - my kids LOVE to come home to find this). It’s those little extras that show how much they care about their work!

Dave I. did an amazing job. I was very impressed by his work ethic and workmanship.
Found and repaired an unexpected problem and fixed promptly. Highly Recommend

I came home to a burst hot water pipe. I panicked and hired Cornerstone to come out for emergency services. In retrospect I should have stayed a couple of nights at the Ritz Carlton, for what I paid. The part of the pipe the burst had a valve on it. The plumber replaced the piping but deleted the valve- so the $1000 I paid for one hour’s worth of work went to waste, since I had to have it all redone the following week. The plumber also went a little hard with the sawzall when removing the burst pipe, and put some scuff marks on a nearby pipe. I’ll give them a couple of stars because they did come out right away and got the water back on, but the $300 bucks you pay to get the guy to your door does not apply to the work they do once they get there, and they shouldn’t be replacing valves pipes with non valve pipes. I wasted a lot of money on this one.

Lost A/C during a hot day in Salem. Cornerstone Services came fast, found the issue, and got it working the same day. They were honest and explained the repair clearly.

Cornerstone Services was great start to finish! The employees were knowledgeable, friendly, and informative. I will definitely use this company again! Highly recommend

Dave was excellent. Very professional & knew exactly what the problem was. Wasn’t expecting the cost but it had to be done.

I was very impressed with this company. They kept me informed about their arrival, did their job above and beyond. Ron was excellent. Also had electricians come and was very pleased with them also. Great company to work with. My previous company never contacted me after my initial call for service so am glad I found Cornerstone

Tom was thorough, personable and quick to get the job done. I'd hire them again and would highly recommend Cornerstone in the future.

Talk about impeccable service and response, we had a near electrical emergency with our fairly new panel and plug/outlet completely frying and they came out within a few hours got us up and running temporarily and safely until a new panel can be installed tomorrow. Thank you thank you thank you!

Used Cornerstone once again today. Had some plumbing issues that needed their attention.Greg came out to the house and was here exactly in the timeframe they said.
Took a look at what needed to be done and explained everything and the price. Once again did a fantastic job. Finished in a very timely manner.
Everyone we have dealt with at Cornerstone really knows their job and they get it done and done right the first time. Absolutely will use them for any future needs we have. Highly recommend!!

Alex did a great job in repairing the concrete holes in the side of my house. He even found other spots and repaired them as well. I am super happy. Thank you. I will be using you for all my repairs.

I was excited about the good reviews of Cornerstone Services. My parents' home falls within their service area (according to both their map and written description), so I took and uploaded photos and details of the job using their portal, only to be told that we fall outside their service area. Please update the description and map or be willing to make exceptions for those who trusted your website.

Arnold was just awesome!!! From the time we met him-got the estimate-to the work being done!!!!!! The work is just wonderful. When he was done with the job it was spotless!!!! Would have this company back in a heartbeat!!!!!! Thank you

We hired Cornerstone to replace some sliding glass doors at our house. Arnold and his team did a fantastic job from start to finish. They came when they said they would be there. They came in on budget. They cleaned up after themselves. The entire team was great to work with. Thank you Cornerstone!

Hired Cornerstone to patch a hole in my ceiling. Alex came up on schedule, was able to provide a quote, and complete the job on the same day. Very happy with the promptness and professionalism he had, as well as the quality of the work performed.

Cornerstone Services is our new "go-to" company for electrical, handyman, HVAC etc, etc. Alex was such a pleasure to have work on our home. He was thorough and explained everything every step of the way. He attended to our home as if it were his own. He was very professional and friendly. The entire staff (including their schedulers) are extremely polite and knowledgeable. They strive to meet the customers needs. We have Ron coming out to service our HVAC problem in the next few days. Highly, highly recommend this company!!!

Very polite women friendly here on time .house smelled amazing and clean they asked questions and made absolutely sure we received what we asked we will definitely use them again.

Ron was great. He quickly identified the problem, explained it to me, corrected the problem
He actually found another problem with the thermostat from the original heat in my home and corrected that
Thanks Ron

Campion Estates was surprised to have our condo common area cleaning completed today(19th) rather than yesterday as had been expected.

Dave replaced our leaking indirect water heater. This was my first experience with Cornerstone, and the entire experience was great. Couldn’t be more pleased! We had an additional visit from Paul for electrical work. Very pleased with his work. Thank you!

Recently Paul did some HVAC work for us. Paul was great - very good work, good communication, on time, on budget. We continue to use Cornerstone because they work out so well for us.

I have been using Conrenstone for about a year for house cleaning and service and quality has been excellent. Recently had them power wash my house as well, and it looks like new. Jason came out promptly to provide an estimate, which turned out to be highly competitive and the job was done quickly and with no disruption to anything on the property. A great choice for home services.

Erin and Nilda always do an amazing job cleaning our home! Everything is sparkling clean, smells so fresh, and the floors are shiny, both the hardwood floors and the tile floors. They also make creative and fun designs out of our bedspread, paper towels, and tissue paper for us to come home too! All this at a reasonable cost. Thank you so much Erin and Nilda for all that you do!

Excited to work with Cornerstone.
UPDATE: Cornerstone Cleaning has been cleaning our church and school properties for several months. Jason and Erin do an amazing job. They are quick to respond when I reach out to them as well as always available to help provide a solution if a situation arises. I would highly recommend them for all of your commercial cleaning needs!

Jason did A great job cleaning all of my windows inside and out. I’m really pleased with the work. I’ve had many different jobs done by Cornerstone and they always do a wonderful job!

Tom was very professional & personable. He found incorrect parts that were used by the previous company! He also discovered an issue with the breaker box that was rigged by the previous owner. Again this was not found by previous companies. I needed a new breaker box and the price was very fair! I highly recommend "Tom" for electrical and Cornerstone services.

Paul is a good electrician. Tom is also a good electrician. Arnold is a good contractor and helped install our bannister and fixed our doors. Mike is helpful with plumbing. We use Cornerstone for a lot of things! ⚡

Josh is awesome!! He left his home and family on the July 4th holiday to restore electric service to our water heater. Above and beyond!! I highly recommend him.

Notice of tech on the way. Arrived on time within appointment. Found the problem quickly and fixed . Professional, reliable service
