"I called Integrity Electrical after several outlets in the house failed, including the one for the refrigerator. Joe responded immediately, figured out the problem, and did a great job of explaining the work that needed to be done. Joe and Alex upgraded the house to 200 amp service, which involved replacing the electrical panel, upgrading outlets, and replacing a meter box that had water damage. I would not hesitate to call them again."

For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

The organization consist of skilled and ambitious craftsmen dedicated to providing unparalleled customer service and quality workmanship.

"The initial build went reasonably well. We did find problems which they did come back and fix. I noticed a railing support that was cracked. I was told that I must of done it, that was that. The plugs that cover the screw holes in the stairs are falling out. I looked for some at Home Depot, but couldn't find the right color. I still had Chase's cell #, so I texted him and asked if he could send me some plugs, and I would do it myself. No response. Tried again the next day, still no response. I'm not surprised. Aging the build was decent, price was higher than most. Now that nearly 2 years have gone by, and customer service should be anticipated, nothing. Never again."

Subcontractors questions, answered by experts

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.

Many providers assist with obtaining necessary permits. Confirm with your contractor.

Most commercial projects take 3-7 days, including curing time, depending on size and weather conditions.

The timeline for building a game room depends on the project’s complexity. Converting an existing room may take one to three weeks, while building a new addition or highly customized space can take several months. Factors such as permitting, material lead times, and contractor availability also impact the project schedule.
