How Our Warranties Works

At MD Contractors, every project we build is backed by our 5-year (or more) workmanship warranty, depending on the type of structure. This warranty is our promise to you that the work we performed was done correctly, safely, and with long-lasting craftsmanship.

Our goal is simple: if something goes wrong because of the way it was installed, we’ll fix it, at no cost to you. Just contact us and let us know what the issue is, we will take care of the rest and honor our warranty. 

Below is an easy summary of how your labor warranty and manufacturer warranty works.

What Our Labor Warranty Covers

Our workmanship (labor) warranty protects you against any issues that occur because of the installation process.

This includes problems caused by:

  • Incorrect installation
  • Improper alignment or leveling
  • Structural issues resulting from labor
  • Components that fail due to workmanship
  • Any part of the project that was not installed according to our standards


In simple terms: if something isn’t right because of how it was built, we’ll come out and make it right, free of charge.

What Our Labor Warranty Does Not Cover

While we stand behind our work 100%, some issues fall outside of what a labor warranty covers, such as:

  • Damage from weather, storms, or natural events
  • Damage caused by misuse, impact, or accidents
  • Wear and tear over time
  • Material defects (covered by the manufacturer’s warranty)
  • Shifting caused by ground movement or soil conditions
  • Changes, repairs, or additions made by another contractor



 

If you’re ever unsure whether something is covered, just contact us, we’re always happy to take a look.

How Long Your Labor Warranty Lasts

Your workmanship warranty lasts a minimum of 5 years, depending on the type of project:

  • Fences: 5 years
  • Patios & Hardscapes: 5 years or more
  • Decks, Porches & Shade Structures: 5 years or more



 

These warranties are some of the strongest in Maryland because we use in-house specialists and do not outsource our work.

Material & Manufacturer Warranties

When investing in a new fence, deck, or patio, it’s reassuring to know that the materials come with solid manufacturer warranties. Below we provide a summary of typical warranty coverage by material type and brand. These warranties underscore the confidence manufacturers have in their products’ longevity.

(Remember: you can always contact us to handle any warranty claims and reinstallations on your behalf, at no cost to you.)

Wood (Pressure-Treated Pine & Cedar)

Wood is naturally durable, and with proper treatment and maintenance, it can last for decades outdoors. While there’s no single manufacturer tied to our wood materials, most pressure-treated and cedar wood products follow standard warranty ranges.

Pressure-Treated Pine

  • Typically covered by a 15-year limited warranty against rot, decay, and termites.
  • Proper sealing and care can extend lifespan to 15–20+ years.
  • Example: YellaWood offers a 15-year limited warranty.

 

Cedar Wood

  • Naturally rot-resistant and does not require chemical treatment.
    Often expected to last 15–20 years with proper upkeep.
    Some mills offer limited warranties (commonly 15 years).

 

For wood products, just contact us if you notice issues, we’ll coordinate the warranty process and reinstall any affected parts if needed.

Composite (Fiberon, Trex, TimberTech, AZEK)

Composite decking and fencing materials are engineered for exceptional durability and come with some of the strongest warranties in the industry, ranging from 25 years to lifetime, depending on the brand and product line.
