"We had our hot water heater replaced and I'm impressed! They didn't charge me extra for calling after 5pm. I was scared of being charged for an emergency call. They texted info of the technician coming to my house. As a woman, I appreciate knowing WHO is coming to my home. I don't want just anybody coming with my child in the house. This is a great family company. They arrived as promised and promptly stopped the old water heater from flooding my garage. My new water heater works great! They fixed my pressure regulator and I can enjoy my house again!"

"I recently purchased a new construction home built by Axe Construction, and I couldn’t be happier with the experience. There were a couple of small hiccups during move-in (as with any new build), but Tomer and the Axe team handled everything quickly, professionally, and without hesitation. Their responsiveness and commitment to making sure I was completely satisfied really stood out. The quality of the construction is excellent — thoughtful layout, great finishes, and solid craftsmanship throughout. It’s clear they take pride in their work. I highly recommend Axe Construction to anyone looking for a trustworthy, high-end builder. They stand behind their product and genuinely care about their clients.

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.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

While some people are confident in their ability to replace concrete by drilling out the broken pieces and replacing them with bagged concrete, it’s possible to run into snags that make hiring a professional worth it. Trying to level concrete slabs can require special equipment, which can be pricey to rent and tough to operate. It's also crucial to contact your town's municipal office to ensure you are allowed to take on the project without a permit.
