Sand mastic for homes and businesses in Piddinghoe
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you are redecorating. If you have failed mastic on an exposed elevation and gaps where the frame meets the masonry, we can put it right, on stone surrounds, sash and case windows and tenement windows alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Piddinghoe is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by our 12-month guarantee.

What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to a full day, depending on how many windows. In a small place like Piddinghoe, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Mention any parking rules near the property

Common questions in Piddinghoe
Will you come out to Piddinghoe?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Newhaven Town station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will it make a mess?

Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Where do you work from?
We work from Crawley. Our applicators cover Piddinghoe, along with the rest of our area.
DIY sealant or a professional job?
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, and the work is guaranteed for a year.
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.
How we quote for sand mastic
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- When we can work, for business premises
- Which sealant suits the joint
- Any mould that needs treating
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
When you contact us, it’s useful to know:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking

- Mastic worn away on windows facing the weather
- Open joints round the window box

What sand mastic looks like in Piddinghoe
Piddinghoe is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Monk's House (about 2.3 miles north) nearby, there’s older building stock in the area around Piddinghoe as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Breakwater Academy, the mastic around its windows and doors needs looking after like any other building’s. Homes close to The Parish Church of St John include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Piddinghoe is about 1 mile north-west of Newhaven, in East Sussex.

How to look after the new joints
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
- Leave the new mastic unpainted
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Leave it or put it right?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Piddinghoe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
