What a Defects-Liability Period and Warranty Cover

Handover is not the end of a serious contractor’s responsibility — it is the start of the part most firms would rather you didn’t ask about. The defects-liability period and the written warranty are what stand behind the build after the contractor leaves site. If you are commissioning a commercial or institutional project, understanding these is how you tell a contractor who is accountable from one who is gone the moment the cheque clears. This article explains them.

What a Defects-Liability Period Is

The defects-liability period (DLP) — sometimes called the maintenance or rectification period — is a defined window after practical completion during which the contractor is obliged to return and put right defects that appear in the work, at the contractor’s cost.

It is a normal, standard provision in a properly written construction contract. During this period:

• The client reports defects that emerge in normal use
• The contractor returns and rectifies them at no cost
• A retention sum (a percentage of the contract value held back) is typically released only after the period closes and outstanding defects are cleared

The DLP exists because some defects only reveal themselves once the building is occupied and put through a full cycle of use and weather — and the contractor, not the client, should carry that risk.

What a Warranty Covers

A warranty is the contractor’s written commitment to the quality of the build, and it typically runs alongside and beyond the DLP. Where the DLP is a contractual rectification window, the warranty is a standing promise that the work was built to specification and to code — to L.I. 1630 and the Ghana Building Code (GS 1207:2018) — and that the contractor will stand behind it.

A written warranty matters because it is evidence of accountability. A firm that puts its warranty in writing is a firm that expects to still be in business — and reachable — when you need it. Many of the brochure-only firms in the market offer nothing of the kind.

DLP vs Warranty — the Difference

They work together: the DLP gives you a defined mechanism in the contract; the warranty gives you a standing assurance.

What These Mean for You as a Buyer

When you evaluate a contractor, treat the DLP and warranty as a trust test:

• Does the contract include a clearly defined defects-liability period?
• Is there a written warranty, not a verbal assurance?
• Is the firm established enough to still be there to honour it? (A contractor since 1977 is a different proposition from one founded last year.)
• Is there a clean handover package — as-builts, certificates, and warranties — so you have the documentation to make a claim if you ever need to?

A contractor who answers these confidently is one who builds expecting to be held to account. That is exactly the contractor you want.
