Your local mastic man for Ashford, Surrey
This is Ashford in Spelthorne, a few miles south of Heathrow and east of Staines-upon-Thames, not its namesake in Kent. Its station on the Waterloo to Reading line is listed as Ashford (Surrey) for exactly that reason. The town has a busy Church Road high street, large residential areas such as Ashford Common, and a lot of households with ties to the airport. Mr Mastic covers Ashford from our base in Crawley.
We reseal baths, showers, basins, kitchens and windows, and the approach never changes: cut out every bit of old sealant, deal with any mould, make sure the joint is dry, then lay a neat new bead with the right Arbo or Everbuild product. If you are wondering how long a reseal should last, our guide on how long silicone sealant lasts is a good place to start.
Semis from 1885 to 1960, and a growing number of flats
Most of Ashford’s houses are detached and semi-detached homes built between 1885 and 1960, as the town grew from a village around St Matthew’s church into a commuter suburb served by the railway. Churches tell the same story: St Hilda’s was built between 1912 and 1928 to serve the growing area around the station. The 2011 Census counted about 4,400 semi-detached houses, 2,400 detached and nearly 1,700 terraced homes.
Flats are a big part of the picture too, with more than 2,600 at the last full count, and the number is rising. The former Ashford County Grammar School buildings on Church Road were bought by Inland Homes, and planning permission was granted for 357 homes on the site. New developments like this usually mean builder sealant that cracks as the building settles in its first year or two.
In the older semis, the usual finds are sealant laid over sealant from past refits, baths that have dropped and opened the joint, and replacement uPVC windows whose mastic has gone hard and grey.

Flats, rentals and the flight path
Ashford has a lower rate of owner occupation than much of Surrey, so a lot of homes are rented, and many of those are flats. A shower seal that fails in an upstairs flat often shows first as a stain on the ceiling below. We can coordinate with managing agents and landlords, sort out access and parking, and leave the bathroom ready to use once the cure time has passed.
Most of the older semis now have replacement windows, and many of the flats were built with uPVC from the start. When the mastic around those frames shrinks or cracks, draughts and damp get in. We cut out the old joint, add backing rod in deeper gaps and reseal with a flexible window and door mastic.
Church Road businesses, airport lets and the hospital
Church Road has supermarkets, coffee shops, estate agents, funeral directors and places to eat, all with staff toilets and kitchens that need sound, hygienic sealant. Ashford Hospital, north of the town centre, and the homes and practices around it, and the many offices and hotels linked to Heathrow, all bring washroom and kitchen sealing work. We can work out of hours for commercial clients.
