"Konnaugh and his team were a pleasure to work with. They showed up on time, and after demolishing and removing a hot tub and a chicken coop, they left my yard practically spotless! They did such a great job, I would highly recommend them to anyone looking for junk removal or yard cleanup ??"

They were very easy to work with. We would absolutely recommend them without hesitation. We plan to hire them again for future projects."

"Kyle and his crew did a great job clearing a wooded/brush area of my backyard and preparing it so I could plant grass. They were knowledgeable, reasonably priced, on time, performed the job as agreed, cleaned up well and Kyle even returned a few days later to take a couple small trees down as promised. He is very conscientious and wants his customer to be satisfied with his work. I would definitely hire K&J contracting again."

FAQs for demolition projects in Merrimack, NH

A complete chimney demolition takes close to five days with a two-person crew; removing only the stack can be completed in half a day. Pros take the structure down brick by brick, add temporary supports if needed, and haul away debris before they leave. Their step-by-step approach safeguards nearby walls and the roof while keeping dust and hazards in check.

Most municipalities require a permit before any part of the chimney comes down. Check with your local building department for the exact fees and paperwork, and confirm any HOA rules that may be applicable. Your structural engineer or chimney professional can obtain the permit on your behalf and ensure that every step complies with local safety and zoning codes.

You can close up your chimney instead of demolishing it. This process involves sealing the damper, installing a chimney cap, and closing the fireplace opening with a secure barrier such as bricks or a door. Closing the chimney maintains the structure while preventing airflow, moisture, and debris entry. This method reduces demolition costs and complies with building code requirements when complete removal is not necessary.

Removing a chimney and switching to modern, eco-friendly alternatives enhances your property’s appeal through increased energy efficiency and potential LEED certification. However, many buyers insist on an operational fireplace, and as a result, removal can reduce overall home value by $5,000. Homeowners should assess market expectations and consult experts to ensure that any changes align with their long-term property goals.

It’s crucial to determine if your chimney is load-bearing before starting removal. Modern homes feature chimneys that are independent of the building’s structure, whereas older homes rely on chimneys for support of critical systems. Review your blueprints or consult a qualified structural engineer to confirm if additional support is necessary. This step ensures safe removal and sound planning.
