Mastic and sealant work in Hindhead
Hindhead is the highest village in Surrey, with its buildings standing between about 185 and 253 metres above sea level on the Greensand Ridge. Height brings weather, and weather is hard on external sealant. Mr Mastic covers Hindhead and Beacon Hill from our base in Crawley, and alongside bathroom and kitchen resealing, much of our work up here is outside: windows, doors, conservatories and the joints between materials that let wind-driven rain in.
Whatever the job, the old sealant is cut out in full rather than covered over. Joints are cleaned and dried, backing rod goes in where the gap is deep, and the new sealant is chosen for the surfaces and the exposure. On glass roofs and large glazed panels, our glazing sealant service uses products made to bond to glass and frame alike.
A late-Victorian hilltop village among the trees
Hindhead grew into a substantial settlement in the late 19th century, and its homes sit along a mix of paved streets and wooded roads. St Alban’s Church on Beacon Hill was built in stages from the early 1900s, as the village filled out. Grayshott adjoins the village, and Haslemere, the parish town, is about two miles to the south-east.
Older houses here tend to have timber windows and doors that have been repaired, painted and sometimes replaced over a century of exposed weather. Where joinery is painted, we use a flexible sealant that can be painted to match; where frames have been swapped for uPVC, the mastic around them is often now hardened, cracked and pulling away from the brick. Extensions and conservatories add yet more joints where old wall meets new.
Inside, bathrooms in big older houses are often spread across several rooms and floors, and timber floors flex under a full bath. We use a flexible sanitary silicone and fill the bath before sealing so the bead copes with that movement. For walk-in showers, our wet room sealing page explains how the floor and wall joints are treated.

Exposed walls, shaded joints and a quieter village
Since the Hindhead Tunnel opened on 29 July 2011, taking the A3 underground, the old road past the Devil’s Punch Bowl has been returned to heathland and the A333 now links the village to the bypass. That has made the centre quieter and easier to work in, with less traffic grime on frames. Height and trees still matter, though. South-west facing walls take the brunt of the rain, while joints in the shade of tall trees stay damp and grow mould and algae.
We check sills, thresholds and fascia joints as well as the frame edges, and our gutter and fascia sealing covers the higher joints that are often overlooked. Where a building has several different materials meeting, our guide to expansion joints explains why the sealant needs room to move.
Schools, holiday lets and village businesses
Commercial work in Hindhead is mostly on a smaller scale than in the towns: shops and cafés in the village centre, schools, care settings and rented homes. Undershaw, once a hotel and now a school, is one example of a large older house given a new use, and buildings like it have washrooms and kitchens that need regular resealing.
The National Trust land around the Punch Bowl and Gibbet Hill draws walkers all year, and if you run a holiday let or guest room nearby, tired bathroom sealant is the kind of detail visitors notice. We can reseal between bookings, and out-of-hours working can be arranged for commercial jobs.

Questions we’re asked in Hindhead
Do you cover all of Hindhead?
Yes. We cover Hindhead and Beacon Hill, plus nearby Grayshott, Haslemere and the villages along the ridge.
Why does the mastic on my windows fail so quickly up here?
Height means more wind-driven rain and bigger temperature swings, and joints under trees stay damp. Cutting out old mastic and using a flexible weatherproof sealant with backing rod gives a longer-lasting joint.
Can you seal a glass conservatory roof?
Yes, where it can be reached safely. We use glazing sealants made to bond to both glass and frame.
My timber windows are painted. Can the new sealant be painted too?
Silicone cannot be painted, so on painted joinery we use a suitable paintable sealant instead.
Can you reseal a holiday let between bookings?
Yes. We plan the work so the sealant can cure before the next guests arrive.
Our bath seal keeps splitting in an old house. Why?
Timber floors flex when a bath is filled. We fill the bath before sealing and use a flexible sanitary silicone so the bead can move with it.
Is the work guaranteed?
Yes. Every job we do comes with a one-year guarantee.
