Gutter sealing in Farnborough, done properly
We work across Farnborough on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we’ll confirm what access is needed. We are often asked to deal with cracked sealant along roofline trims and damp patches inside below a leaking gutter, on roofline trims, gutter joints and uPVC fascias.
Older homes in small places like Farnborough may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take anything from an hour or two to a few hours. Somewhere like Farnborough needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- The area is dried so the sealant can bond.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we’re there.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Farnborough questions
Do you cover Farnborough for gutter sealing?
Yes. We work across London and the South East, and Farnborough is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Is Farnborough within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Surface by surface
Roofline trims
Trims along the roofline are often finished with sealant. Split sealant lets water in.
Soffit joints
Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.
Outside joints around Farnborough
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we quote for gutter sealing
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- Whether the work is at height
- How many areas need sealing
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved.
What happens if it’s left?
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it has failed, we’ll tell you. Around Farnborough, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Aftercare tips
To keep the joints looking good and working properly:
- Have sagging gutters refixed early
- Make sure downpipes are not blocked
- Watch the wall under the gutters for staining
- Get leaks sealed before the wet months
Look at fascia and trim joints when you’re checking the gutters. A small split is quicker to put right.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards and the wall below.
When to call us in Farnborough
Sagging sections pull joints apart. Sealing will not hold if the gutter keeps dropping so the brackets need attention first.
Most people get in touch after spotting one of these:
- Failed sealant on a garage door frame
- End caps that drip every time it rains
- Damp on an inside wall under a dripping gutter
- Old sealant on roofline trims that has split
Around Farnborough, as everywhere, gutter sealing is only as good as the preparation behind it.
What your quote should include
- Whether they’re fully insured
- Who turns up on the day
- Which colour the sealant will be
- Which sealant they’ll use, and why
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
