Windows and doors in Shenington
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Upton House (about 1.9 miles north) nearby, there’s older building stock in the area around Shenington 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.
Schools such as Shenington Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

About our sand mastic in Shenington
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have mastic that needs renewing before redecorating and modern sealant on a period surround, we can put it right, whatever the surface.
Around Shenington, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job, whatever its size.

Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Shenington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Landlord and commercial work in Shenington
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Damaged stone surrounds
- Whether work needs listed building consent
- Sashes that rattle, stick or won’t open
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Keeping the joints in good condition
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Don’t run silicone over sand mastic
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Common questions in Shenington
Is there a guarantee on sand mastic in Shenington?
All our work, in Shenington and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Shenington within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Are you fully insured?
Yes. We are fully insured.
The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere like Shenington needs a little journey planning: 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 start by checking each surround and agreeing the joints to renew.
- 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.
How to prepare
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
