Sand mastic for homes and businesses in Park Wood
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you have mastic dropping out of the joint and wind and rain getting in round a sash window, we can put it right, on sash and case windows, period & listed homes and tenement windows alike.
Around Park Wood, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
We stand behind the work with a 12-month guarantee.

Why deal with it now?
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 Park Wood, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Clear gutters so water does not pour onto the windows
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

When to call us in Park Wood
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber and we normally remove them.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Wind and rain getting in round a sash window
- Open joints round the window box
- Cement or filler used on old window joints that has cracked
If you live in an older home near St Paul's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. Parking around Park Wood is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare

Park Wood homes and the weather
Historic houses like Restoration House (about 4.9 miles north-west) are a reminder that the area around Park Wood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Rainham (Kent) station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Park Wood Infant School? Then its window and door frames need their mastic kept sound, just like a home’s.
