Our Services

Deck Construction

Want to add a new outdoor living space or replace an aging deck? We use the highest-quality materials, craftsmanship, and follow-up to build the deck of your dreams. Custom design an outdoor living space that complements your home design and exceeds your expectations. If your existing deck has a structurally sound framework, we can replace failing steps, boards, or railings to improve both safety and appearance. We work with a variety of wood materials, plus low-maintenance PVC or composite, so you can update your deck to refresh your home’s appearance. For new, damaged, and deteriorated decks, our deck construction services can provide the support you need.

Wood Fences

Wooden fences are a beautiful addition to any home and yard. Over time, however, exposure to sun, harsh winter weather, and natural aging can degrade the stability and appearance of the materials used. If you’ve noticed mildew, grime, flaking, peeling, graying, or fading, your fence is at risk of falling apart and needs immediate care. We can restore your fence by cleaning, sanding, and resealing the boards. This treatment restores elasticity, durability, and beauty to your fence, maintaining your home’s curb appeal. Use our cost-effective maintenance services to retain your wood fence’s value for years to come.

Deck Lighting

Enhance your outdoor living space with a customized, energy-efficient lighting plan designed for your year-round needs. Deck lighting allows you to enjoy your outdoor living space at any time of day or night, so you can stay outside for as long as you want. With our deck lighting services, you can choose from a variety of lights to find the options that best fit your aesthetic and needs. Our design and installation experts provide guidance for posts, rails, stairs, and overhead lighting. We also provide full-service holiday lighting for your home and business. Complete your outdoor living space with tasteful deck lighting.

What Our Customers are Saying

The workmanship was really good, and I am very happy with the service.

Quy Nguyen

Good work and convenient logistics at a good price.

Jeremy England

Seal-A-Deck did an excellent job on my deck. They were responsible, friendly and skilled at their job. Everything was on-time and well done - the deck looks great.

Arnie Harris

I would need a pad of lined paper to take down all my accolades for the job that Seal-A-Deck did on my backyard deck. I have never been the recipient of a construction-restructuring job in which everything went very smoothly, and I felt taken care of at each step in the process. I appreciate that enormously. From beginning to end and even after completion, the courtesy calls, the follow up and the follow through were simply as good as it gets. The power wash and cleaning, the people performing the work, and the product at the end of the process with staining were all as close to perfect as I could have dreamed. I wish Seal-A-Deck could teach their customer service to every company out there!

Linda Brown

Seal-A-Deck did a terrific job. Their work was meticulous, they came when they said they would, they finished on time, the team was polite and professional, and most importantly, the end product looks great. I would recommend them highly.

Cai Von Rumohr

We had several pieces of teak furniture refinished. Very professional, reliable, and qualified. Would use them again in a minute.

Danielle White

Seal-A-Deck is a wonderful company! I would highly recommend using them for your decking needs. I had a deck that needed restoration. They did a fantastic job cleaning, sanding and staining the deck! It looks brand new!

Jim Peptipas

True professionals! Our deck, although fairly new, was not sealed properly by another contractor last year. As a result, we had severe discoloration/mold that left the wood in complete ruin. The Seal-A-Deck crew came in and treated the mold, sanded down and renewed the wood to its original state, and stained it to perfection! Would gladly use them for maintenance for many years to come and strongly recommend them to anyone who needs their deck to shine again.

Chitra Lefevre

We were so happy with the way our deck came out! The color we picked was just right! With so many companies being busy right now, Seal-A-Deck came through and made time for our project. The results were outstanding as shown in the pictures attached. They were quick, efficient, and pleasant to converse with. We cannot thank Seal-A-Deck enough for the work they did!

Stephanie Barbosa

We recently had our deck rebuilt. Everything went smoothly from the time we spoke with Frank to get the design together. We were put on the schedule promptly and kept informed of all details. The finished product was beautiful, and we can't wait to use it. Thank you, Frank, Nicole, Evelyn and the entire team. Fair price and great work.
