- Internal damp traced to a gutter joint
How we handle gutter sealing in Horn Hill
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we will tell you. If you’re dealing with failed sealant on a garage door frame and dripping gutter ends, we can help, on uPVC fascias, soffit joints and gutter end caps alike.
In a village or hamlet like Horn Hill, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why act early in Horn Hill
You do not need to replace a garage door because rain gets in round the frame. Resealing the frame joint is often enough. Older cottages and farmhouses around Horn Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Rest ladders on the wall, not the gutter
- Keep an eye out for wet patches below a joint
- Sort out a dripping joint early
- Look along the fascias for open joints
Look at fascia and trim joints when you’re checking the gutters. A small split is quicker to put right.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- A gutter length that has split
- Gutters that have dropped or pulled away
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
What we seal

How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes an hour or two for a few joints, longer for a full run in most cases.

Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.

Horn Hill buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Chenies Manor House (about 3.6 miles north) are a reminder that the area around Horn Hill has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around St Paul's, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Maple Cross Junior Mixed Infant and Nursery School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
