Gutter sealing in Seaton, done properly
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough if the gutter is not damaged. We work on soffit joints, garage door frames and gutter joints, and people most often call us about gaps along fascia and soffit joints and trim joints where the sealant has failed.
In a village or hamlet like Seaton, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, it’s backed by our 12-month guarantee in Seaton and across Kent.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What happens if it’s left?
You don’t need new fascias just because the joints have opened. A neat seal closes the gaps as long as the boards are in good condition. In a small place like Seaton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Seaton in your area for gutter sealing?
Yes. Our work covers London and the South East, and Seaton is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Is it possible to stop a gutter joint dripping with sealant?
In most cases, yes. A sagging or cracked gutter needs more than sealant, and we will tell you.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Seaton, along with the rest of our area.
What does gutter sealing cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. Each joint is cleaned and sealed.
Common problems we fix in Seaton
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits over time.
These are the problems we’re asked about most:
- Old sealant on roofline trims that has split
- Quick sealant fixes on gutters that didn’t last
- Rain getting in around a garage door
- Water running down the wall below the gutter
For an older house near a landmark such as Church of St Andrew, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before booking anyone
- Is VAT in the price?
- What product goes in the joint
- Whether you can choose the colour
- How the surfaces are prepared before sealing
Keeping the joints in good condition
So the new joints stay in good condition:
- Look along the fascias for open joints
- Look at the gutters while it’s raining
- Watch the wall under the gutters for staining
- Sort out a dripping joint early
Keep the gutters clear of leaves and moss, so water drains away past 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 inside.
How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a few hours in most cases. In a small place like Seaton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Gutter sealing in Seaton: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodnestone Park (about 3.2 miles south-east) are a reminder that the area around Seaton has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Wickhambreaux Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Bekesbourne station? Then leaking gutter joints on a rental are best caught before they stain the walls.
