10 Year Warranties

Builders Warranty On New Homes

Builders Warranty

A builders warranty is also known as a developers warranty or home builders warranty. It is a first party insurance policy that covers new build properties, commercial units & conversion schemes.

The builder or developer of the property typically takes out the warranty, with the builder being the insured party, and the property owner the beneficiary of the policy.

Typically, a 10 year builders warranty is split into two periods. The first two years is known as the defects insurance period. During this time, the builder is responsible for fixing any issues that may arise, this includes structural defects as well as workmanship issues. The second part is called the structural insurance period. During this time, the insurer is responsible for the cost of correcting any structural issues.

Those undertaking self build projects and intending to live in the property often see professional consultants certificate as a cost effective solution.

Home builders warranty FAQs

Why should I buy builders warranty insurance?

Rectifying structural defects can be both time-consuming and expensive – having a builders warranty in place offers peace of mind that should any defects be found, it will be rectified at no additional cost or having the need to show negligence.

Having this piece of insurance also makes the property more appealing to potential buyers, as they won’t be burdened with the costs of structural repairs within the warranty period.

Also, it is often a stipulation by mortgage lenders that such a cover is in place – this means that prospective buyers might have challenges securing a mortgage for the property without a builders warranty. Moreover, you could face challenges obtaining the necessary funds for the initial construction without the warranty being in place.

How does a builders warranty work?

Although it is recommended to purchase a builders warranty before construction commences, a builders warranty can also be secured retrospectively.

During the initial two years post- practical completion, your builder assumes responsibility for repairs and addressing snags.

Starting from the third year, the warranty provider takes on the financial burden of structural repairs, such as roof replacement. This offers reassurance to potential buyers, sparing them from shouldering the expenses associated with these vital repairs.

What does a builders warranty cover?

A builder’s warranty typically covers defects and issues with a newly constructed home for a period after  practical completion. While the exact coverage can vary, a typical home builders warranty covers:

  • Workmanship and Materials: This includes defects related to the quality of construction work and materials used in the home.
  • Mechanical Systems: Warranties often cover issues with essential systems like plumbing, electrical, and HVAC (heating, ventilation, and air conditioning).
  • Water Intrusion: Problems related to water leaks and damage, including damage from faulty windows or roofing, may be covered.
  • Appliances and Fixtures: Some warranties extend to appliances and fixtures provided by the builder.
  • Code Compliance: Builders are typically required to ensure that the home meets local building codes, and warranties may cover issues related to code compliance.
  • Roofing and Exterior: Coverage can include issues with the roof, siding, and exterior components of the house.
  • Dampness and Condensation: In some cases, warranties cover problems like dampness and condensation, but usually only if they result from builder negligence.

The defect liability period (DLP) lasts between 12 and 24 months from the completion of the construction work – depending on the contract. During this time, the builder is responsible for the defects that occur within your property and the surrounding communal areas.

During this defects liability period, also known as the ‘snagging period’, the builder is responsible for defects arising from workmanship, substandard materials, or other construction-related issues.
