Sealant jobs we do in Headley Down
Headley Down is a village in the parish of Headley, in East Hampshire, about a mile east of Headley itself, with Grayshott to the east and Churt to the north. It sits on high, heathy ground next to Ludshott Common, and its houses are spread along roads laid out in a grid more than a century ago. Mr Mastic covers Headley Down from our base in Crawley.
We reseal baths, showers and kitchens, replace window and door mastic, and seal external joints. Each job starts with getting all the old sealant out, because new silicone cannot bond to old. Then the joint is cleaned, dried and sealed with a product suited to the surface and the way it moves. If you want to know what good preparation involves, our guide to choosing a mastic man sets out the questions worth asking.
Victorian retreats, a 1970s estate and newer closes
From about the 1870s, people began building houses here to live or holiday in the healthy air of the Hindhead area, and by 1909 the side roads had been laid out in a grid. Some of those older detached houses still stand, often on large plots among the trees. Over the 20th century the village grew past Headley’s parish centre.
The biggest single change was the Heatherlands estate, about 350 houses built on the site of a former camp and finished by 1977. It now houses about a fifth of the parish. Houses of that age are on their third or fourth bathroom in many cases, and the sealant from earlier refits is often still there under the newer bead. Later closes, such as Penryn Drive and Stonedene Close, replaced older houses and a children’s home in the 1980s and after, and there is also the Windmill Estate and the older Land of Nod estate to the north.
Across all of these, the common jobs are mouldy shower seals, bath joints that have split, and uPVC frames whose mastic has gone hard. Older detached houses can also have timber windows and doors, where we use sealants suited to timber and paintable products if the joint is to be painted.

Homes among the trees and on the heath
Many Headley Down homes sit among trees, with Ludshott Common, a large National Trust heath, along the eastern and southern edge of the village. Tree cover keeps walls and windows shaded and damp, and needles and leaf litter collect on sills and around frames. Old mastic in those spots stays wet, grows mould and breaks down. We clean back to sound surfaces and use a flexible window and door mastic that holds up to the damp.
Inside, shaded bathrooms dry slowly, so black mould on sealant is a common call-out. Anti-fungal silicone, good ventilation and wiping the joint after a shower all help it last, and we will talk you through the simple habits that keep it looking new.
Village shops, churches and rented homes
Headley Down is mainly residential, with a small number of shops, such as the One Stop on the Heatherlands estate and the petrol station store on the old Beech Hill Garage site, plus St Francis Community Church. Toilets and kitchens in shops and community buildings need resealing now and then, and out-of-hours working can be arranged.
We also work for landlords with rented homes here and in nearby Bordon and Grayshott, resealing between tenancies.

Headley Down: common questions
Do you cover all of Headley Down?
Yes. We cover the whole village, including the Heatherlands estate, the Windmill Estate and the Land of Nod, plus Headley, Grayshott, Churt and Bordon.
My house is on the Heatherlands estate. Is the sealant likely to need replacing?
If it has not been redone for some years, probably. We remove all the old layers and reseal with anti-fungal silicone.
Why does the mastic on my shaded windows go green or black?
Shade and damp from trees keep the joint wet, so mould grows. We clean back, then use a flexible weatherproof sealant.
Can you seal around wooden windows?
Yes. We use sealants suited to timber, and a paintable product where the joint needs painting.
Is Headley Down too far out for you?
No. We cover East Hampshire from our base in Crawley, and we plan the visit so the job is finished in one trip where possible.
Do you work for landlords?
Yes. We reseal between tenancies and can quote for several properties together.
How long does a shower reseal take?
Usually a few hours, and the shower can be used after about 24 hours.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
