About our gutter sealing in Horsleys Green
For gutter sealant to hold, the joint has to be clean and dry. That’s why we take out the old sealant and dirt first, then dry the joint before sealing. If you have cracked sealant along roofline trims and rain getting in around a garage door, we can help, whatever the surface.
Older homes in small places like Horsleys Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The process
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. The work normally takes a few hours, depending on the number of joints and the access. In a small place like Horsleys Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.

How the job changes by surface
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Soffit joints
Gaps at soffit joints can let in draughts and insects. We close them with a suitable sealant.
Why act early in Horsleys Green
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Where a wall is exposed, as many are in small places like Horsleys Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
