What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed.
Which is right for my windows, sand mastic or modern sealant?
We’ll help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.

How we handle sand mastic in Hundridge
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. Typical jobs include patchy fillers round a sash window and draughts and rain around sash boxes, across period & listed homes, brick reveals and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Hundridge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same one-year guarantee in Hundridge and across Buckinghamshire.

Landlords and agents in Hundridge can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
What we do, step by step
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours per window, depending on the condition of the joints. Somewhere as small as Hundridge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Putty and glazing repairs
- Whether work needs listed building consent
- Sashes that need overhauling
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
Joints and surfaces we work on
- Timber door frames
- Tenement windows
- Stone surrounds
- Brick reveals
- Sash and case windows
- Period & listed homes

Keeping the joints in good condition
Aftercare is simple:
- Keep modern sealant off the mastic
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Different surfaces, different methods
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Why it’s worth doing now in Hundridge
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Hundridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

How we quote for sand mastic

- Working hours on commercial sites
- Any mould that needs treating
- How easy the joints are to reach
- The product the joint needs
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Whether it has been sealed before
- The address or postcode of the job
- Roughly how big the job is
- Any access issues, like height or stairs
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Hundridge homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Cholesbury Manor House (about 3.4 miles north) nearby, there’s older building stock in the area around Hundridge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Hyde Heath Infant School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Great Missenden station, older sash windows in a rental need their mastic kept sound to keep the weather out.
