Looking for deck repair contractors? Deck repair contractors can help you with deck problems, from small aesthetic issues to larger structural problems, to get your deck back in shape.

Before you start deciding which contractor is the right one for your repair job, it’s important to first understand what deck problems warrant a search for deck repair contractors.

The problems to look for vary, depending on:

  • If you have a wood deck.
  • If you have a composite deck.

A Brief Look at Deck Anatomy

Before we jump into tips for recognizing deck issues, you first need to know basic deck anatomy.

Deck Anatomy Overview

All decks, whether wooden or composite, are made up of:

  • A substructure, which includes the joists, beams, blockings, and posts that secure the deck.
  • A deck surface, which includes the deck boards and railing, if your deck has one.

When to Call a Contractor: Problems to Look for

For both wood and composite decks, you should perform an annual deck inspection to check for problems with the substructure and deck surface.

Common Problems With Wood Decks: Surface & Substructure

Traditional wood, as an organic material, is highly vulnerable to moisture and weathering damage, and so is apt to have the following problems.

Moldy wood can weaken your deck

Rot, Mold, & Mildew

Caused by moisture, all of these can weaken your deck’s structure.

Signs of a problem:

  • A greenish tint.
  • Black or white fuzzy areas.
  • Soft, spongy wood.
Traditional wood cracks, splinters, & warps

Cracking & Warping

Usually caused by the penetration and rapid evaporation of moisture.

Signs of a problem:

  • Cracks or splinters that continue to grow.
  • Boards that look bent between fastenings.
Wood decks may feature rusted or loose fasteners

Rusted or Loose Fasteners

Can occur in the deck surface, substructure, and railing.

Signs of a problem:

  • Rusted screw or nail heads.
  • Wobbly railing.
  • Protruding nails or screws.

Common Problems With Composite Decks: Surface & Substructure

If you have a TimberTech® composite deck, your boards are moisture- and weather-resistant thanks to protective capping, so they are unlikely to have moisture or wear-and-tear related issues.

Still, your deck’s substructure is made of wood, so be sure to check the substructure regularly for the problems listed above.

Deciding When to Do a Replacement Rather Than Repairs

Deck repair contractors that come out to see your deck should give you an estimate. The estimate will tell you what the repairs entail and what they will cost, giving you an idea of repair costs against which you can weigh replacement costs.

Indicators it may be better to go for a replacement rather than repairs include:


You may want to replace if the cost for your deck repairs gets high enough to be equivalent to replacement costs.


If your deck is damaged, and the damage to your deck makes it structurally unsound.


If your current deck no longer serves your and your family’s needs, it may be time to upgrade.

If one or more of these indicators are met, there are two ways you can go about replacing your deck: deck resurfacing or full deck replacement.

Deck Resurfacing

Deck Repair Contractors for Wood or Composite Decking

Deck resurfacing is where the existing substructure of your deck stays and only the deck boards are replaced. Deck resurfacing can be done only if the substructure is in good condition. You’ll also need to be happy with your deck’s current shape, size, and decking pattern.

Benefits of Resurfacing

  • Cost-effectiveness: Using the existing substructure saves you both labor and material costs.
  • Less time to replace: Using your existing substructure saves time, so you can get back to enjoying your deck faster.

Full Deck Replacement

Deck repair contractors can help with complex decks

A full deck replacement is where both the substructure and the deck surface are completely replaced. A full replacement is necessary if the substructure is damaged beyond repair. It’s also essential if you plan on making significant changes to your deck’s shape, size, or decking pattern.

Benefits of a Full Deck Replacement

  • Design freedom: A full deck replacement gives you full rein to redesign your deck just how you want it.
  • Better function: A new custom-built deck is bound to better meet your needs so you can enjoy your deck in whatever way you want.

Considerations for Deck Resurfacing & Replacement

Resurfacing or replacement jobs bring up a few more concerns than simple repairs, namely, what decking material to use, and which deck repair contractors have the experience your build needs.

Choose Durable Deck Material for a Longer Lasting Deck

Instead of choosing the same traditional wood decking that’s bound to require additional repair and replacement over time, level-up with TimberTech® composite decking. Our durable deck material is designed with the nature-inspired beauty of wood, and none of wood’s drawbacks.
