Gutter sealing for homes and businesses in Penhurst
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame with an exterior sealant. We work on gutter end caps, gutter joints and soffit joints, and the jobs we see most are rain getting in around a garage door and fascia boards with gaps between them.
Outside joints can only be sealed when they’re dry, so work in Penhurst is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, whatever its size.

What we are called out for in Penhurst
Sealant laid on a wet or dirty joint fails early. Some quick repairs peel off within a season or two.
The most common problems we see are:
- Gaps along fascia and soffit joints
- Old gutter sealant that has let go
- Water running down the wall below the gutter
- Damp on an inside wall under a dripping gutter
If you live in an older home near The Parish Church of St Michael, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- What preparation is included
- What happens if the job turns out different
- How much experience the applicator has
- Is the old sealant removed completely?
Different surfaces, different methods
uPVC fascias
Open fascia joints look untidy and can let water in. Sealing them closes the gap.
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Downpipes that are blocked or broken
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Rotten or damaged fascia boards
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The process
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from an hour or two to a few hours, depending on the size of the job. Somewhere as small as Penhurst, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need sealing.
- We clean out each joint.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
Before we arrive
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

Walls and rooflines in Penhurst
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Bateman's (about 4.7 miles north) nearby, there’s older building stock in the area around Penhurst as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

How long will you be here?
Typically it takes anything from an hour or two to a few hours. Bigger jobs take longer.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Where are you based?

Can you reach high gutters?
That depends on the building. Let us know the height and the ground below and we’ll confirm what’s needed.
