DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How we handle gutter sealing in Kingwood Common
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough if the gutter isn’t damaged. If you have fascia boards with gaps between them and old sealant on roofline trims that has split, we can put it right, on garage door frames, soffit joints and roofline trims alike.
Outside joints can only be sealed when they’re dry, so work in Kingwood Common is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take an hour or two for a few joints, longer for a full run. Somewhere as small as Kingwood Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we trace the drip and check the gutter isn’t damaged.
- 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.
- The gutter is checked and debris around the joints cleared.

Leave it or put it right?
A new garage door is not needed for a leaking frame. Sealing the frame usually stops it, if the frame itself is sound. Where a wall is exposed, as many are in small places like Kingwood Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t lean ladders against the gutter itself
- Check fascia and soffit joints for gaps
- Watch for drips in a downpour
- Look for streaks or damp on the wall below gutters
Check the joints after heavy rain now and then. It’s the easiest time to see a leak.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job while the frame is sound.
What the job involves on each surface
Gutter joints
A gutter joint has to cope with movement and standing water. A gutter sealant made for the job holds best.
Gutter end caps
End caps are resealed where they meet the gutter once clean and dry.
Kingwood Common buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Greys Court (about 1.9 miles north-east) are a reminder that the area around Kingwood Common has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Henley-On-Thames station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. For an older house near a landmark such as The Church of Christ the King, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Peppard Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
