Gutter, fascia & soffit sealing in Furnace Green, West Sussex
Gutter sealing for Furnace Green and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- End caps that drip every time it rains
- Garage door frames letting rain in
- Leaking gutter joints and stop ends
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Check fascia and soffit joints for gaps
- Keep ladders off the guttering
- Get leaks sealed before the wet months
- Clear leaves and moss from the gutters
Keep downpipes clear, so water can get away. A blocked pipe backs water up to the joints.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp.
How we handle gutter sealing in Furnace Green
We don’t replace gutters, fascias or roofs. Sealant fixes joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. We work on roofline trims, gutter joints and soffit joints, and people most often call us about internal damp traced to a gutter joint and dripping gutter ends.
Homes around Furnace Green range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Our work is backed for twelve months, in Furnace Green and everywhere else we cover.

What affects the quote in Furnace Green
We do not publish a price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it has been sealed before
- Roughly how big the job is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or email us.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the 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.

Why deal with it now?
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. In a smaller place like Furnace Green, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Furnace Green buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Crawley, which Furnace Green is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time.
Rented homes near Three Bridges station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near St Andrew's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Brook Infant School, larger buildings have long runs of movement joint that eventually need resealing.
Furnace Green is about 2 miles south-east of Crawley, in West Sussex. Furnace Green gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 371 towns and villages across West Sussex.

Furnace Green questions
Do older homes in Furnace Green need their sealant replacing?
Often, yes: cracked, shrunken or mouldy sealant has done its job. The key is cutting all the old sealant out, as new sealant won’t bond to it.
Do you cover smaller places like Furnace Green?
Yes. Furnace Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can a leaking gutter joint be sealed?
Most of the time. If the gutter is sagging or cracked, sealing won’t last and we will say so.
What should I tell you?
Let us know what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does gutter sealing take?
Most jobs take anything from an hour or two to a few hours, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is gutter cleaning part of the job?
We clear what’s around the joints we work on. A full clean of the gutters isn’t part of it.
What guarantee comes with the job?
Our 12-month guarantee applies on every job.
