How the job changes by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
How we handle sand mastic in Billingshurst
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. We’re often asked to deal with modern sealant on a period surround and tired mastic found when preparing windows for paint, on sash and case windows, period & listed homes and timber door frames.
In a smaller place like Billingshurst, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
We stand behind the work with a one-year guarantee.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. Parking around Billingshurst is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Advice
Windows and doors in Billingshurst
Historic houses like Old Place Manor (about 4.9 miles south-west) are a reminder that the area around Billingshurst has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Billingshurst Unitarian Chapel, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Billingshurst station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a smaller place like Billingshurst, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why us?
- Neat joints and a tidy finish
- We never seal over old sealant
- Arbo and Everbuild products
- Anti-fungal silicone where joints get wet

What we’re called out for in Billingshurst
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Signs it’s time to call us include:
- Cracked mastic round a front door frame
- Draughts and rain around sash boxes
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
For site and facilities teams at buildings such as Billingshurst Primary School, its window and door frames need their mastic kept sound, just like a home’s.
