Gutter sealing in Plaistow, done properly
Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on soffit joints, roofline trims and gutter end caps, and people most often call us about leaking gutter joints and stop ends and internal damp traced to a gutter joint.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Plaistow, tell us how high the joints are and how to reach the back of the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Your questions about gutter sealing in Plaistow
Do you work for landlords with property near West Ham station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is parking a problem for a job in Plaistow?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you have insurance?
Yes. We’re fully insured.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can you seal fascia and soffit joints?
Yes. Open joints along uPVC fascias and soffits can be sealed in a matching colour.
Can you reach high gutters?
It depends on the access. Tell us the height and what’s around the gutter when you ring 0345 464 0079 or drop us an email.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Plaistow buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Queen's House (about 3.2 miles south) are a reminder that the area around Plaistow 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.
If you live in an older home near Memorial Community Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. As a London address, Plaistow can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near West Ham station, leaking gutter joints on a rental are best caught before they stain the walls.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Have sagging gutters refixed early
- Watch for drips in a downpour
- Clean out the gutters once or twice a year
- Keep an eye out for wet patches below a joint
Leave the new sealant to cure as we advise before poking or cleaning near it.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
What the job involves on each surface
Gutter joints
A gutter joint has to cope with movement and standing water. A gutter sealant made for the job holds best.
Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.
How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take an hour or two for a few joints, longer for a full run. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Plaistow. It helps if you can point us to a visitor permit or a bay close to the door.
- First we trace the drip and check the gutter is not damaged.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
How to get a quote

When it isn’t the sealant
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Brackets that have snapped or loosened
- Cracked, split or warped gutter sections
- Blocked downpipes
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
