Assessing the Chimney

Before initiating repairs or waterproofing, thoroughly inspect your chimney to identify any damage or potential areas of concern. Look for cracked or deteriorating mortar, damaged bricks, crumbling masonry or loose flashing. Additionally, check for signs of water stains or leaks on the interior walls near the chimney. A comprehensive assessment will guide you in determining the necessary repairs and waterproofing measures.

While homeowners can safely complete visual inspections from the ground, we advise calling a professional for a close-up inspection, as they will have the right safety and access equipment.

Repair and Waterproofing Methods

There are various types of chimney repairs and waterproofing methods. The service you need will depend on the condition of your chimney and any specific problems. The roofers at AFB Builders will advise on the right option for your Farnham home, which could include the following:

Brick Repointing and Replacement

Deteriorated mortar and damaged bricks compromise the integrity of the chimney, allowing water to penetrate. Chimney repointing involves removing and replacing the damaged mortar to create a strong seal. If bricks are badly damaged, they may need to be replaced. Occasionally it may be easier to complete an entire chimney replacement, but this will be discussed with you in advance, following a thorough inspection.

Leadwork Replacement or Repair

Lead flashing is a crucial component that seals the intersection between the chimney and the roof, preventing water from entering. Over time, flashing can deteriorate, become loose or develop gaps. Repair or replace damaged flashing to maintain a watertight seal.

Waterproofing Sealants

Applying a waterproofing sealant is an effective measure to protect the chimney from water damage. Waterproofing sealants create a barrier that repels water while allowing the chimney to breathe. It's important to choose a high-quality waterproofing product suitable for the specific chimney material.

Chimney Cap Replacement

A chimney cap acts as a protective barrier, preventing water, debris and animals from entering the chimney. Chimney repairs often involve replacing damaged or missing chimney caps, an essential step in preventing water damage. A cap that is appropriate for your chimney size and design will ensure proper ventilation and protection.

Regular Maintenance

Once repairs and waterproofing are complete, regular maintenance is crucial to preserve the integrity of your chimney. Schedule annual inspections by professional Farnham contractors to promptly identify and address any emerging issues.
