Gutter, fascia & soffit sealing in Forest Gate, Greater London
Problem with your gutter and fascia joints in Forest Gate? We remove the old material, prepare the joints and seal them properly.
- Damp patches inside below a leaking gutter
- Quick sealant fixes on gutters that didn’t last
- Dripping gutter ends
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep the gutters clear of debris
- Check the gutters during heavy rain
- Deal with a drip before winter
- Make sure downpipes are not blocked
Keep downpipes clear so the gutter can drain. Blockages push water back along the gutter.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
How we handle gutter sealing in Forest Gate
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where one is available. If you’re dealing with quick sealant fixes on gutters that didn’t last and drips from gutter joints and end caps, we can put it right, on gutter end caps, soffit joints and gutter joints alike.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Forest Gate, tell us how high the joints are and how to reach the back of the building.

What gutter sealing looks like in Forest Gate
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Valentines Mansion (about 2.2 miles north-east) nearby, there’s older building stock in the area around Forest Gate as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near A Radical Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Wanstead Park station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

The joint between frame and brickwork moves and weathers. We use a sealant made for outdoor joints.
uPVC fascias
Gaps in fascias spoil the roofline. Sealing them closes the gap.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the number of joints and the access, and the area is left clean.

- First we trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Forest Gate questions
Can parking be tricky for a visit in Forest Gate?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Wanstead Park station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Forest Gate, along with the rest of our area.
Do you work in Forest Gate?
Yes. We are based in Crawley and work across South East England, London and Scotland.
Do you seal gaps in fascias and soffits?
Yes. We seal open joints along fascias and soffits in a matching colour.
Do you work on high-level gutters?
Low gutters are simple to reach. If it’s higher up, let us know and we’ll confirm the access.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can I do it myself?
If you are set on DIY, put the effort into 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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
