DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Gutter sealing in Boyn Hill, done properly
We work across Boyn Hill on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach, and for higher work, tell us about access and we’ll confirm what’s needed. We are often asked to deal with internal damp traced to a gutter joint and earlier gutter repairs that have peeled off, across soffit joints, garage door frames and roofline trims.
Houses in smaller places like Boyn Hill can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
Each job carries a 12-month guarantee, whatever its size.

How the job changes by surface
Roofline trims
We reseal trim joints with an exterior sealant.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the number of joints and the access. In a smaller place like Boyn Hill, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we are there.
Before we arrive
- Tell us about any water getting in
- Mention any tricky access
- Try not to wet indoor joints just before the visit

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Make sure downpipes aren’t blocked
- Clear leaves and moss from the gutters
- Watch for drips in a downpour
- Glance at the soffit joints now and then
Keep the gutters clear of leaves and moss so water does not sit on the joints. Water left in a gutter tests every joint.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp.

Walls and rooflines in Boyn Hill
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 Dorney Court (about 3.1 miles east) are a reminder that the area around Boyn 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.
Managing a site like Larchfield Primary and Nursery School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around All Saints' Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Maidenhead station, leaking gutter joints on a rental are best caught before they stain the walls.

Leave it or put it right?
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Homes in smaller places like Boyn Hill can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
