Welcome to Andrade Sealcoating - The sealcoating and pothole repair specialists you can count on.

Andrade Sealcoating is a sealcoating and asphalt repair company based in Alton Bay, New Hampshire. Our company is a family run business which started in 2009 and has continued to grow ever since. We serve clients all over New Hampshire and the majority of our clients come from referrals.

We take pride in the work that we do and build a relationship with our clients. We also provide a follow-up service every two years by calling our clients to see if their asphalt needs our attention after the harsh winters New Hampshire gives us each year.

Here at Andrade Sealcoating, our constant goal is to deliver total client satisfaction with the products and services we offer, regardless of how big or small the tasks are.

Andrade Sealcoating offers competitive pricing and outstanding service with the work being completed by the company's owners themselves. We use Neyra Tarconite Asphalt Pavement Sealer with a deep, rich, black seal that offers lasting beauty and protection. We also fill cracks, repair potholes, and do line striping for our commercial clients.

While we provide a wide range of services for both commercial and residential customers, a large part of our clientele are home owners who enjoy the stress-free process of our services.

Our services include, but are not limited to:

  • Residential and commercial asphalt repair
  • Sealcoating
  • Crack filling
  • Line striping

We serve the majority of New Hampshire with the major part of our business coming from the lakes region area (Alton, Laconia, Belmont, Sanbornton, Moultonborough, Wolfeboro, Ossippee) and Conway Areas.

Since our company is a dedicated asphalt maintenance and repair company, we do not deal with the asphalt paving part of our industry. Therefore, we can focus on the quality of our work and maintaining the asphalt for our clients.
