How we handle sand mastic in Woburn
Across Woburn, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you are dealing with weathered mastic on the most exposed windows and window mastic to renew ahead of painting, we can put it right, on timber door frames, stone surrounds and sash and case windows alike.
Somewhere as small as Woburn, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Every job comes with a 12-month guarantee.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. In a small place like Woburn, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

What sand mastic looks like in Woburn
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Woburn Abbey (about 1.1 miles south-east) are a reminder that the area around Woburn has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Aspley Guise station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Woburn Lower School? Then the mastic around its windows and doors needs looking after like any other building’s.

Do you need sand mastic in Woburn?
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Signs it’s time to call us include:
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
- Cracked mastic round a front door frame
- Gaps where the frame meets the masonry
For an older house near a landmark such as Old Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Keeping the joints in good condition
So the new joints stay in good condition:
- Check with your local planning authority if your home is listed
- Get any rot dealt with first
- Do not paint over the new mastic
- Plan mastic work ahead of painting
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why act early in Woburn
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like Woburn, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
