Gutter sealing for homes and businesses in Three Mills
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. If you’re dealing with leaking gutter joints and stop ends and earlier gutter repairs that have peeled off, we can help.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Three Mills, check the lease for who looks after the outside.
Every job comes with a 12-month guarantee.

Most people get in touch when they notice one of these:
- Leaking gutter joints and stop ends
- Internal damp traced to a gutter joint
- Old gutter sealant that has let go
- Fascia boards with gaps between them
As a London address, Three Mills can be tricky for parking: let us know about parking bays, permits or a driveway.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Look along the fascias for open joints
- Watch for drips in a downpour
- Clear leaves and moss from the gutters
- Get a dropping gutter looked at quickly
Look at fascia and trim joints when you’re 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.

FAQs for Three Mills
Is Three Mills in your area for gutter sealing?

Is parking a problem for a job in Three Mills?
Parking in Three Mills, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
We work from Crawley. We cover Three Mills and the rest of Greater London.
How much does gutter sealing cost in Three Mills?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Leave it or put it right?
A new garage door isn’t needed for a leaking frame. Sealing the frame generally stops it. In a flat in Three Mills, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email and we will talk you through it.

Gutter sealing in Three Mills: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Sutton House (about 2.4 miles north-west) are a reminder that the area around Three Mills has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like East London Science School? Then its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to West Ham station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the number of joints and the access. In Three Mills, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- 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.
Getting ready for the visit
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
