Ware homes and the weather
With historic houses such as Goodnestone Park (about 4.3 miles south-west) nearby, there’s older building stock in the area around Ware as well as newer homes. 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Historic houses such as Goodnestone Park, about 4.3 miles south-west, show how far back building around Ware goes. Rented homes near Minster station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Ware, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t run silicone over sand mastic
- Don’t paint over the new mastic
- Check the mastic when you check the paintwork
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
