Resealing and mastic work across Hillingdon
Hillingdon is London’s westernmost borough and one of its largest, stretching from the green, suburban north around Northwood, Ruislip and Harefield down to Hayes, West Drayton and Heathrow. Mr Mastic is based in Crawley and covers every part of it, resealing bathrooms and kitchens, replacing window and door mastic and sealing joints on homes, offices and hotels.
Most of our work here is in family houses that have had the same sealant for far too long, or in newer flats where the original sealant has given up early. Either way, we never put fresh silicone over old. We cut the old bead out, clean and prepare the joint, then apply a neat, flexible finish using sealant matched to the job, whether that is anti-fungal silicone in a shower or a weatherproof mastic around a patio door. Before anything starts, you’ll get a clear quote.
Metro-land houses in the north, new flats in the south
The north of the borough grew up around the Metropolitan Railway’s line to Uxbridge, the heart of what became known as Metro-land. Ruislip Manor is a good example: George Ball built his “Manor Homes” estate there between 1933 and 1939, aimed at working people buying their first house. Eastcote, Ickenham, Northwood and Ruislip are full of similar interwar semis and detached houses, and the borough also has 31 conservation areas protecting its older village centres.
In 1930s houses, the bathroom has usually been replaced at least once, and the joints around baths and basins have often been resealed over old silicone. Original timber windows have mostly given way to uPVC, and after a couple of decades the mastic around those frames goes hard, shrinks and lets draughts and damp in. Our window and door mastic page explains how we replace it.
In the south, Hayes, Yiewsley and West Drayton have seen their industrial past replaced by housing. The Old Vinyl Factory in Hayes, has been redeveloped with new homes, and new blocks have gone up around the stations. Fresh plaster, settling floors and daily use mean developer sealant in these flats often fails within a year or two.
Suburban semis, conservation villages and new blocks
Much of Hillingdon is houses rather than flats, so access is usually easy, with off-road parking and no shared hallways. The main question in the conservation areas of Ruislip, Eastcote, Harefield and Northwood is appearance: we keep beads slim and colours sympathetic on older frames.
In the newer blocks around Hayes, West Drayton and Uxbridge, we plan visits around parking, lifts and entry fobs, and take extra care with flats below. Around the borough’s replacement windows, the perimeter sealant is part of keeping the frame draught-proof and weathertight, so we renew it with a flexible, weatherproof product rather than patching over cracks.
Heathrow hotels, business parks and Brunel
Heathrow Airport sits within Hillingdon, and the hotels around it have hundreds of guest bathrooms in constant use. Shower and bath seals in rooms like these fail far sooner than at home, and we reseal room by room so rooms go back into service quickly. Our hotel sealant page explains how we work.
The borough also has large office sites, including Stockley Park and Uxbridge Business Park, plus Brunel University in Uxbridge and Uxbridge College in Uxbridge and Hayes. Hillingdon Hospital, which is due to be redeveloped, has clinics and care homes around it. Landlords and letting agents call us for resealing between tenancies across the borough.

What we do in Hillingdon
- Bathroom & kitchen resealing: Baths, showers, basins, wet rooms, worktops and sinks: old sealant cut out, mould treated and a new bead of anti-fungal silicone laid.
- Window & door mastic: Frame perimeters inside and out resealed with flexible, colour-matched sealant, with backing rod where the gap is deep.
- Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.
- Remedial sealant & repairs: Messy, layered or wrong-product sealant cut out and replaced with the right sealant, laid the right way.
- Fire-rated sealant: Fire-rated sealant for service penetrations and frame gaps where it has been specified, applied to the tested details.
- External & façade joints: Split or perished joints in walls and cladding replaced with exterior sealant designed to stretch with the building.
- New-build mastic & snagging: Failed builder sealant in new homes put right, and plot mastic for developers.
- Floor & skirting joints: Floor and skirting joints in homes, shops and warehouses sealed neatly and to the right depth.
- Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.
- Glazing & conservatory sealant: Glazing joints on conservatories, roof lanterns and screens renewed with a sealant suited to glass and frames.
- Gutter, fascia & soffit sealing: Dripping gutter joints and end caps, and gaps at fascias and soffits, sealed with weatherproof exterior sealant.
- Sand mastic for sash & case windows: Traditional sand mastic for period windows and doors where a modern sealant would look out of place.

Questions we’re asked in Hillingdon
Do you cover all of Hillingdon?
Yes. We cover Uxbridge, Hayes, Ruislip, Eastcote, Ickenham, Northwood, Harefield, West Drayton, Yiewsley, Harlington and the Heathrow villages.
Our 1930s Ruislip semi has old sealant over older sealant. Can you fix it?
Yes. We remove every layer back to a clean surface and reseal, because new silicone won’t bond properly over old.
Can you reseal hotel bathrooms near Heathrow without closing a whole floor?
Yes. We work room by room, so each room can be handed back once the sealant has cured.
Do you work on business parks like Stockley Park?
Yes. We reseal staff kitchens, shower rooms and washrooms, and out-of-hours working can be arranged.
The mastic round our uPVC windows has gone hard and cracked. Is that a big job?
It’s a common one. We cut out the old mastic, clean the frame and apply a flexible, weatherproof sealant in a colour to match.
Do you work in new flats in Hayes and West Drayton?
Yes. We often replace developer sealant in showers and kitchens that has split as a new building settles.
Can you reseal student or rented properties near Brunel?
Yes. We work with landlords and letting agents and can fit the job in between tenancies.
