Gutter sealing for homes and businesses in South Newington
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough if the gutter is not damaged. Typical jobs include water running down the wall below the gutter and end caps that drip every time it rains, on roofline trims, gutter joints and garage door frames.
External sealant needs dry, clean surfaces, so work around South Newington is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

South Newington buildings and the weather
With historic houses such as Broughton Castle (about 3.1 miles north) nearby, there’s older building stock in the area around South Newington as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around South Newington, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

When to call us in South Newington
A sealant applied to a damp or dirty joint will not bond. Some quick repairs peel off within a season or two for this reason.
Look out for these signs:
- Failed sealant on a garage door frame
- Internal damp traced to a gutter joint
- Dripping gutter ends
- Fascia boards with gaps between them
In the older streets around St Peter ad Vincula, an extension built onto an older house moves differently, and the joint between them takes the strain.

South Newington questions
What guarantee comes with gutter sealing in South Newington?
All our work, in South Newington and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is South Newington in your area for gutter sealing?
Yes. Our work covers London and the South East, and South Newington is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is gutter cleaning part of the job?
The joints we seal are cleaned out and clear debris we find nearby. A full gutter clean is a separate service.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Is sealant enough for a gutter that has dropped?
Not on its own. If the gutter sags, the joints keep opening so it needs refixing before sealing.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Why act early in South Newington
If the problem is a blocked downpipe, sealing won’t help. We check the cause first and point you to the right trade if needed. In a small place like South Newington, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured.
Looking after it afterwards
Looking after new joints is easy:
- Have sagging gutters refixed early
- Don’t lean ladders against the gutter itself
- Keep the gutters clear of debris
- Look along the fascias for open joints
Keep the gutters clear of leaves and moss, so water drains away past the joints. Standing water strains every seal.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
What we do, step by step
When we get to you, we compare the joints with what we discussed. 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. For a village or hamlet like South Newington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we are there.
Before we arrive
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
