External mastic for homes and businesses in Wooden Hill
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on brickwork movement joints, joints between brick and frames and concrete & block, and common reasons people get in touch are joints with sealant missing in places and hard, crazed mastic that has stopped moving.
Somewhere as small as Wooden Hill, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, you get the same one-year guarantee.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

FAQs for Wooden Hill
Do older homes in Wooden Hill need their sealant replacing?
Often, yes: cracked, shrunken or mouldy sealant has done its job. The key is cutting all the old sealant out, as new sealant won’t bond to it.
Do you work for landlords with property near Bracknell station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

Outside joints around Wooden Hill
Bracknell, which Wooden Hill is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so whole streets can have gutters, trims and wall joints reaching the end of their life together. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Wooden Hill Primary and Nursery School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St Michael and St Mary Magdalene's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Bracknell station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
