Why it’s worth doing now in Brockley
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Brockley, the repair is bigger than the sealant job would have been.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Gutter sealing for homes and businesses in Brockley
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s joint work, not replacing the gutter. We work on soffit joints, garage door frames and roofline trims, and common reasons people get in touch are stop ends leaking at the end of a run and damp patches inside below a leaking gutter.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Brockley, it’s worth checking who is responsible for the outside before booking.
There’s a 12-month guarantee on every job.

What we can’t put right
To be straight with you, some problems need a different trade:
- Brackets that have snapped or loosened
- Downpipes that are blocked or broken
- Guttering that needs replacing
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

What the job involves on each surface
Roofline trims
Trims along the roofline are often finished with sealant. Split sealant lets water in.
Garage door frames
Resealing a garage door frame keeps rain and draughts out.
What affects the quote in Brockley
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The amount of work
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Helping us quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- A few photos by email, if you can
- The address or postcode of the job
- Whether it has been sealed before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or send us an email.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Look at the gutters while it’s raining
- Make sure downpipes aren’t blocked
- Get leaks sealed before the wet months
- Keep an eye out for wet patches below a joint
Make sure downpipes are not blocked so the gutter can drain. Blockages push water back along the gutter.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take 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 Brockley. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- 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.
Before we arrive
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Advice
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

FAQs for Brockley
Can you do gutter sealing in Brockley?
Yes. We work across London and the South East, and Brockley is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Is parking a problem for a job in Brockley?
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.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Is sealing fascia joints something you do?
Yes. Our work is the joints, and if a board is damaged, we’ll tell you.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Will sealing fix a sagging gutter?
Not for long. The joint will pull apart so the gutter has to be refixed first.
Do you work on high-level gutters?
Low gutters are simple to reach. For higher work, tell us about access and we will confirm what’s needed.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What gutter sealing looks like in Brockley
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. 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.
For site and facilities teams at buildings such as Beecroft Garden Primary, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St Hilda, older walls, gutters and the joints where extensions meet them need a flexible sealant. As a London address, Brockley can be tricky for parking: let us know about parking bays, permits or a driveway.
