Gutter sealing in Hammersmith, done properly
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. We are often asked to deal with leaking gutter joints and stop ends and rain getting in around a garage door, across gutter joints, soffit joints and gutter end caps.
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.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why it’s worth doing now in Hammersmith
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Cleaning out and drying the joint first is what makes it last. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Hammersmith.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What else we do in Hammersmith
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Clear leaves and moss from the gutters
- Keep an eye out for wet patches below a joint
- Rest ladders on the wall, not the gutter
- Look at the gutters while it’s raining
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.
Landlords, agents and businesses in Hammersmith
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
The process
We keep the work tidy and contained to the joints we’re treating. Expect the work to take an hour or two for a few joints, longer for a full run. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
How to prepare
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Hammersmith buildings and the weather
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Kelmscott House (about 0.5 miles south-west) nearby, there’s older building stock in the area around Hammersmith as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Hammersmith is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Letting a property close to Kensington Olympia station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. In the older streets around Church of the Holy Innocents, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Hammersmith
I let a flat near Kensington Olympia station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can you do gutter sealing in Hammersmith?
Yes. We work across London and the South East, and Hammersmith is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can a leaking gutter joint be sealed?
In many cases, yes. Cleaning, drying and resealing the joint normally works. A split or warped section needs replacing.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you seal gaps in fascias and soffits?
Yes, often alongside gutter joints. The gaps are cleaned and sealed neatly with a suitable exterior sealant.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
