Gutter sealing in Handcross
Failed sealant round a garage door frame lets rain blow in. The frame joint is cut out and resealed with an exterior sealant. We work on roofline trims, soffit joints and gutter end caps, and people most often call us about leaking gutter joints and stop ends and failed sealant on a garage door frame.
Older homes in small places like Handcross may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Whatever the size of the job, it’s backed by our 12-month guarantee in Handcross and across West Sussex.

Common questions in Handcross
Do you work for landlords with property near Balcombe station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Do you cover smaller places like Handcross?
Yes. Handcross is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Will sealant fix a dripping gutter joint?
In most cases, yes. If the gutter is sagging or cracked, sealing won’t last, and we’ll tell you.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
What affects the quote in Handcross
We do not publish a price list. The quote depends on:
- The size of the job
- Mould in or behind the old joints
- The old material and how stubborn it is
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- The rough size of the job

The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take an hour or two for a few joints, longer for a full run. In a small place like Handcross, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

Related advice
What gutter sealing looks like in Handcross
Historic houses like Tyes Place (about 1.9 miles south-east) are a reminder that the area around Handcross 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Handcross Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear leaves and moss from the gutters
- Do not lean ladders against the gutter itself
- Keep downpipes clear
- Watch for drips in a downpour
Give the sealant the cure time we tell you and avoid disturbing it.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
Why deal with it now?
You don’t need new fascias just because the joints have opened. A neat seal closes the gaps as long as the boards are in good condition. Older cottages and farmhouses around Handcross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.

Surface by surface
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
Gutter joints
Most gutter leaks start at a joint between sections. We clean, dry and reseal them.
What we are called out for in Handcross
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
Look out for any of the following:
- Rain getting in around a garage door
- Water running down the wall below the gutter
- Internal damp traced to a gutter joint
- Old gutter sealant that has let go
Letting a property close to Balcombe station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
