Alfold Sand Mastic
Our applicators work in Alfold on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.

Sand mastic in Alfold, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. We work on sash and case windows, tenement windows and timber door frames, and people most often call us about open joints round the window box and tired mastic found when preparing windows for paint.
Outdoor sealant needs dry, clean surfaces, so work on frames around Alfold is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
You get a 12-month guarantee, the same in Alfold as everywhere else we work.

How it works
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 the area is left clean. For a village or hamlet like Alfold, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

In and around Alfold, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. For an older house near a landmark such as Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Quotes for sand mastic in Alfold
Your quote is based on your job. We look at:
- The number of rooms or windows
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- What’s wrong with the joints now
- A few pictures by email, if you can
- Whether it has been sealed before
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand.
Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Alfold, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Looking after it afterwards
To keep the joints looking good and working properly:
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
