Gutter sealing in West Ham
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first, then dry the joint before sealing. We work on uPVC fascias, roofline trims and garage door frames, and common reasons people get in touch are streaks down the brickwork from a leaking joint and leaking gutter joints and stop ends.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
Each job carries a 12-month guarantee, whatever its size.

Surface by surface
Gutter end caps
Stop ends hold back water at the end of a run. When their seal fails, they drip.
Soffit joints
Soffit board joints can separate over time. We seal them to close the gaps.

In total, it usually takes a few hours, depending on the number of joints and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in West Ham. It helps if you can point us to a visitor permit or a bay close to the door.

Advice
Quotes for gutter sealing in West Ham
The quote reflects the job in front of us. We look at:
- Whether there’s mould to deal with
- Working hours on commercial sites
- Access and height
- The old material and how stubborn it is
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Where the job is, and your postcode
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Gutter sealing in West Ham: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Sutton House (about 2.9 miles west) nearby, there’s older building stock in the area around West Ham as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
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. Managing a site like West Ham Church Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Common questions in West Ham
Is West Ham in your area for gutter sealing?
Yes, West Ham is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Do you work for landlords with property near West Ham station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
What does gutter sealing cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is gutter cleaning part of the job?
Only around the joints we seal, so the sealant can bond. A full gutter clean is a separate job.
What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Problems with the roof covering
- Boards that have decayed or split
- A gutter length that has split
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Why deal with it now?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp, so it’s worth sealing early. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
