Sand mastic in Davington
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have wind and rain getting in round a sash window and old sand mastic that has cracked, crumbled or fallen out, we can put it right, whatever the surface.
Around Davington, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
Whatever the size of the job, you get the same one-year guarantee in Davington and across Kent.

When to call us in Davington
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
These are the problems we’re asked about most:
- Mastic worn away on windows facing the weather
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
- Silicone on a period window that looks wrong
Managing a site like Davington Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- How long to leave it before use
- The length of the guarantee
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it

What else we do in Davington
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
- Ask the planning authority about consent for listed or conservation-area homes
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Can I do it myself?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Windows and doors in Davington
Davington is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Belmont House and Gardens (about 3.7 miles south-west) nearby, there’s older building stock in the area around Davington as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Faversham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Mary Magdalene, the joint between an old wall and a newer frame is usually the first place rain gets in.

What’s near Davington

Why act early in Davington
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 an older home around Davington, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

How the job changes by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Davington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.

Advice
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Sash cords, weights and draught-proofing of the sashes
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
