How we handle sand mastic in Mott's Mill
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. If you have window mastic to renew ahead of painting and draughts and rain around sash boxes, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Mott's Mill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Why it’s worth doing now in Mott's Mill
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Mott's Mill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
Why book with us
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely
- ARBOMaster approved applicator
- We are fully insured
Aftercare tips
Looking after new joints is easy:
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere as small as Mott's Mill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Tell us about any water getting in
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Sand mastic in Mott's Mill: local notes
With historic houses such as Groombridge Place (about 1.6 miles north-east) nearby, there’s older building stock in the area around Mott's Mill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Groombridge St Thomas' Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Eridge station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around Church of St Thomas the Apostle, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
