Your questions about sand mastic in Ibworth
I let a flat near Overton station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Ibworth within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you guarantee sand mastic work?

Sand mastic in Ibworth
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. We’re often asked to deal with wind and rain getting in round a sash window and cracked mastic round a front door frame, on period & listed homes, brick reveals and timber door frames.
Homes in small places like Ibworth often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Ibworth and everywhere else we cover.

Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Where a wall is exposed, as many are in small places like Ibworth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

Windows and doors in Ibworth
With historic houses such as The Vyne (about 4.8 miles north-east) nearby, there’s older building stock in the area around Ibworth as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Signs you need sand mastic in Ibworth
Rain on the window surround works into any crack and loosens it further. Exposed elevations generally fail first.
Keep an eye out for any of the following:
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
- Gaps round a timber door in stone or brick
The Vyne, about 4.8 miles north-east, is one of the historic houses in the wider area around Ibworth, and older homes nearby need a sealant that suits their walls.
Before you book anyone
- Which colour the sealant will be
- How much experience the applicator has
- Whether VAT is included
- What guarantee comes with the work
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Honest limits
Sealant is not the answer to every problem, and we will tell you before we start. It will not solve:
- Timber that has rotted
- Whether work needs listed building consent
- Broken panes
