Sand mastic in Bardfield End Green, done properly

Around Bardfield End Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

When to call us in Bardfield End Green
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
The problems people generally mention when they call include:
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
- Failed mastic on an exposed elevation
Horham Hall, about 2.6 miles west, is one of the historic houses in the wider area around Bardfield End Green, and older homes nearby need a sealant that suits their walls.
What your quote should include
- Are they insured?
- Is VAT in the price?
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Bardfield End Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

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. After that, the work takes a few hours for a single window, longer for several. For a village or hamlet like Bardfield End Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions

Related advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Bardfield End Green homes and the weather
Historic houses like Horham Hall (about 2.6 miles west) are a reminder that the area around Bardfield End Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Managing a site like Thaxted Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Bardfield End Green
Will you come out to Bardfield End Green?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on sand mastic in Bardfield End Green?
All our work, in Bardfield End Green and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
