- Damp patches inside below a leaking gutter

- Quick sealant fixes on gutters that didn’t last
Leave it or put it right?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Parsons Green, the repair is bigger than a sealant job.

Gutter sealing for homes and businesses in Parsons Green
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first, then dry the joint before sealing. We work on roofline trims, garage door frames and gutter end caps, and the jobs we see most are water dripping where gutter sections meet and open joints in fascias and soffits.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Parsons Green, tell us how high the joints are and how to reach the back of the building.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

How the visit works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes an hour or two for a few joints, longer for a full run, depending on the size of the job. 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.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- Old sealant and dirt are removed from the joint.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
How to prepare
- Keep children and pets away from the work area
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Advice
Gutter sealing in Parsons Green: local notes
Historic houses like Fulham Palace (about 0.8 miles west) are a reminder that the area around Parsons Green 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. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
If you look after a building such as Lady Margaret School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Imperial Wharf station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Homes close to St Dionis include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Quotes for gutter sealing in Parsons Green
Jobs vary more than people expect. What affects the quote:
- Any working-time requirements on site
- Access and height
- The product the joint needs
- Mould in or behind the old joints
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it has been sealed before
- Whether it’s a home or a business
- Photos by email, if that’s easy
- What’s wrong with the joints now
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or drop us an email with the details.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Get leaks sealed before the wet months
- Clean out the gutters once or twice a year
- Keep downpipes clear
- Have sagging gutters refixed early
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Water left in a gutter tests every joint.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
