Gutter sealing in Newchapel, done properly
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. If you’re dealing with leaking gutter joints and stop ends and cracked sealant along roofline trims, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Newchapel is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Common problems we fix in Newchapel
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up, which is why we look before we seal.
Any of these means the joints need attention:
- Damp on an inside wall under a dripping gutter
- Quick sealant fixes on gutters that didn’t last
- End caps that drip every time it rains
- Trim joints where the sealant has failed
Managing a site like Imberhorne School? Then larger buildings have long runs of movement joint that eventually need resealing.

Questions from Newchapel
Do you cover Newchapel for gutter sealing?
Yes, Newchapel is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you cover smaller places like Newchapel?
Yes, Newchapel is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Where do you work from?
Mr Mastic is based in Crawley. We cover Newchapel and the rest of Surrey, along with the rest of our area.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. The gaps are cleaned and sealed neatly with a suitable exterior sealant.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Sagging gutters or broken brackets
- A gutter length that has split
- Blocked downpipes
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job generally takes an hour or two for a few joints, longer for a full run, and we explain the cure time before we leave. Somewhere like Newchapel needs a little journey planning: let us know about lanes, gates and parking. 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 is not broken or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we’re there.
Preparing for the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Move anything stored near the joints

Outside joints around Newchapel

Historic houses like Saint Hill Manor (about 4 miles south) are a reminder that the area around Newchapel has older buildings as well as new.

How the job changes by surface
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
Soffit joints
Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.
Looking after it afterwards
So the new joints stay in good condition:
- Look for streaks or damp on the wall below gutters
- Look at the gutters while it’s raining
- Make sure downpipes are not blocked
- Sort out a dripping joint early
Look at fascia and trim joints when you are checking the gutters. Splits are easier to seal early.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.
