Chiddingly Window Mastic
Mastic around window and door frames, sills and patio doors for Chiddingly, backed by a one-year guarantee. Call for a quick quote.
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- Draughty joints inside around the window
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Make sure the drainage slots are not blocked
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Avoid blasting the frames with a pressure washer
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Window mastic in Chiddingly, done properly
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. Typical jobs include whistling draughts around closed windows and damp patches on the reveal after heavy rain, across timber windows & doors, aluminium frames and window sills.
Around Chiddingly, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the quote in Chiddingly
We quote each job individually. These are the things that affect it:
- Which sealant suits the joint
- The number of rooms or windows
- The old material and how stubborn it is
- Whether there’s mould to deal with
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or drop us an email with the details, and pictures are welcome.
Window mastic in Chiddingly: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Horselunges Manor (about 2.7 miles south-east) are a reminder that the area around Chiddingly has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Chiddingly Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near The Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Chiddingly is about 4 miles north-west of Hailsham, in East Sussex. Chiddingly gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 289 towns and villages across East Sussex. We also work in Brighton, about 15 miles from Chiddingly.
Here we cover the BN8 postcode area for window mastic. We also cover Whitesmith (1 mile west), East Hoathly (2 miles north-west), Halland (3 miles north-west), Shortgate (3 miles west) and Blackboys (4 miles north). Within a short drive, we also cover Eastbourne (9 miles south-east), Bexhill-on-Sea (13 miles east), Seaford (10 miles south), Lewes (8 miles west), Hailsham (4 miles south-east) and Crowborough (10 miles north).
Landmarks near Chiddingly

Nearby you’ll also find Sussex Farm Museum (2.8 miles north-east) and Tickerage Castle (4.8 miles north-west). Open spaces near Chiddingly include Selwyns Wood.
What happens if it’s left?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we’ll tell you. Around Chiddingly, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Common problems we fix in Chiddingly
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Signs it’s time to call us include:
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
For landlords with property near Berwick (Sussex) station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- How the joint is cleaned and prepared
- How hidden problems are handled
- What the cure time is
- Which colour the sealant will be
Can I do it myself?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
