Frames and glazing around Woodmansterne
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. With historic houses such as Nonsuch Mansion (about 3.9 miles north-west) nearby, there’s older building stock in the area around Woodmansterne as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Peter's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Chipstead station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Sand mastic in Woodmansterne, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Common call-outs are for failed mastic on an exposed elevation and modern sealant on a period surround, on period & listed homes, tenement windows and sash and case windows.
In smaller places like Woodmansterne, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In an older home around Woodmansterne, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What does sand mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Where is Mr Mastic based?

The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job usually takes a few hours for a single window, longer for several. A visit to Woodmansterne is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in

Related advice
What we’re called out for in Woodmansterne
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
Keep an eye out for any of the following:
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
For site and facilities teams at buildings such as Chipstead Valley Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Which sealant they’ll use, and why
- Are they insured?
- Whether you can choose the colour
- Is the old sealant removed completely?
Looking after it afterwards
After the cure time, these simple habits help:
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Don’t run silicone over sand mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
