Deck Sealing in Ellicott City, Columbia, and Annapolis

Your home’s deck is a valuable addition that needs care and maintenance like any other part of your home. Deck sealing is a process that preserves and beautifies your deck while extending its life, as it protects against the elements and helps minimize scratches and scrapes. When you have your deck sealed properly by a professional, it becomes water-resistant and stays looking new—longer! Diamond Decks offers deck sealing services for homeowners in the Ellicott City, Columbia, Annapolis, and Baltimore areas of Maryland.

Benefits of Deck Sealing

When you come to Diamond Decks to have your deck sealed it:

Reduces deck maintenance – Exposed wood on your deck is vulnerable to the elements which will damage the wood. When you have your deck professionally sealed, the wood is no longer prone to damage, thus needing less or no repairs.

Adds longevity – Since your deck has a tight seal, it’s protected from damage and can weather the elements, both which add to the life expectancy of your deck. The longer your deck lasts, the less decks and deck repairs you will need in the long-term.

Prevents damage  Damage such as warping, rotting, cracking, or splintering are eliminated when you have your deck sealed. Nothing can penetrate past the seal, down into the wood, so your deck is free from warp, rot, cracks, and splinters.

Strengthens wood – Wood strength is increased with a deck seal as the wood has an extra layer of protection and stabilization. The wood lasts longer and is a safer surface to walk or place objects onto.

Guarantees Longevity  Ask about our guarantees and warranties that are included in Diamond Decks’ sealing jobs. This gives you peace of mind while protecting your investment.

Seals Deep Into Wood – Deck sealing is not just a surface treatment, it also sinks deep into the wood and fortifies your deck wood for long lasting results. Your deck now has protection against all climate conditions.

The Best Time to Seal Your Deck

The best time to seal your deck is at the end of the summer, once the sun has had a chance to dry out the wood and before the cold and inclement weather of winter set in. If your deck came with a glaze from the mill where it was made, it’s best to let that wear off some before we apply a seal for you.

It’s also best to seal your deck once the water content of the wood is at its lowest point—you don’t want to seal in any moisture. We have the tools and the know-how to take accurate readings, to ensure the best time to seal your deck, so you can achieve the best results.
