Gutter joints
Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily in a suitable colour.
Gutter sealing in Crews Hill, done properly
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on garage door frames, gutter joints and roofline trims, and people most often call us about dripping gutter ends and earlier gutter repairs that have peeled off.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
Big or small, you get the same 12-month guarantee.

Crews Hill questions
Is parking a problem for a job in Crews Hill?
Parking in Crews Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near Crews Hill station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is sealing fascia joints something you do?
Yes. Open joints along uPVC fascias and soffits can be sealed in a colour to suit.
What guarantee comes with the job?
There’s a 12-month guarantee on every job.
What does gutter sealing cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Where are you based?
Mr Mastic is based in Crawley. We cover Crews Hill and the rest of Greater London, along with the rest of our area.
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes 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 Crews Hill. 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.
- The joint is dried, because sealant will not bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
How to prepare
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Common problems we fix in Crews Hill
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end.
Keep an eye out for these signs:
- Cracked sealant along roofline trims
- Dripping gutter ends
- Quick sealant fixes on gutters that didn’t last
- Damp patches inside below a leaking gutter
If you look after a building such as St John's CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Before booking anyone
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
What gutter sealing looks like in Crews Hill
Historic houses like Forty Hall (about 1.5 miles south-east) are a reminder that the area around Crews Hill has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Crews Hill station, leaking gutter joints on a rental are best caught before they stain the walls. Crews Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why act early in Crews Hill
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right compared with treating damp later. 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 Crews Hill, the repair is bigger than the sealant job would have been.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
