Landlords, agents and businesses in Mottisfont
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How we handle sand mastic in Mottisfont
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you are dealing with old cement repairs round a window that have failed and draughty sash windows at the surround, we can put it right.
Somewhere as small as Mottisfont, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Around Mottisfont, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

What sand mastic looks like in Mottisfont
Historic houses like Mottisfont Abbey (about 0.2 miles north-east) are a reminder that the area around Mottisfont 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Mottisfont & Dunbridge station, any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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 fails, we can still redo it.
What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. For a village or hamlet like Mottisfont, 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Keep pets and children clear of the area while we work
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Signs you need sand mastic in Mottisfont
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
Keep an eye out for any of the following:
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps round a timber door in stone or brick
If you live in an older home near Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in.

Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
What should I tell you?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
