Gutter sealing for homes and businesses in Seal
We work across Seal on leaking gutter joints and roofline trims. Low-level work is straightforward, and for higher work, tell us about access and we’ll confirm what’s needed. We work on gutter end caps, uPVC fascias and roofline trims, and common reasons people get in touch are failed sealant on a garage door frame and fascia boards with gaps between them.
Older homes in small places like Seal may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job, whatever its size.

- The number and length of the joints
- Mould in or behind the old joints
- The product the joint needs
- Whether the work is at height
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Outside joints around Seal
Historic houses like Knole House (about 1.8 miles south) are a reminder that the area around Seal 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bat & Ball station, leaking gutter joints on a rental are best caught before they stain the walls. Homes close to Church of St Peter and St Paul include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

What the job involves on each surface
Soffit joints
Open soffit joints let draughts in. We close them with a suitable sealant.
Garage door frames
Frame-to-brick joints face the weather. We use a sealant made for outdoor joints.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes an hour or two for a few joints, longer for a full run and we leave things clean and tidy. In a small place like Seal, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- On commercial sites, let us know about site rules

Common problems we fix in Seal
Sealant laid on a wet or dirty joint fails early. Rushed repairs often do not last long.
Most people get in touch after spotting something like this:
- Wet patches on the wall under a gutter joint
- Damp patches inside below a leaking gutter
- Dripping gutter ends
- Cracked sealant along roofline trims
If you look after a building such as Seal Church of England Voluntary Controlled Primary School, larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- Who turns up on the day
- Is VAT in the price?
- Which colour the sealant will be
- What guarantee comes with the work
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Get leaks sealed before the wet months
- Make sure downpipes are not blocked
- Look for streaks or damp on the wall below gutters
- Glance at the soffit joints now and then
If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
