Sealant jobs we do in Swanley

Swanley sits at Junction 3 of the M25, about 16 miles south-east of central London, and it is a young town by Kent standards. Before the railway arrived in 1861, there was little more than a crossroads with three houses; most of what stands today was built between the post-war years and the late 1980s. Mr Mastic covers Swanley from our base in Crawley, a quick run round the M25.

We reseal baths, showers, sinks and kitchen worktops, replace mastic around windows and doors, and look after rented homes for landlords. There are no shortcuts: old sealant out, mould treated, joint dried and a new bead laid properly. If you’re weighing up who to call, our guide to choosing a mastic man sets out what to ask.

A post-war town with plenty of second-time bathrooms

Because so much of Swanley was built in a few decades after the war, many homes are of similar age, and many have now had their bathrooms and kitchens refitted at least once. That brings its own sealant problems. We often find two or three layers of old silicone around a bath, gaps where a newer, lighter bath has been set on an older floor, and tiles that no longer meet the bath edge evenly. All of it comes out before the new bead goes in.

The town centre was built in the 1970s, after older Victorian houses and shops were cleared, and remodelled in the 1990s. Social housing is concentrated on two main estates, St Mary’s and White Oak, largely provided by West Kent Housing Association. In flats and maisonettes, bathrooms are compact and showers get daily use, so seals around trays and screens wear quickly.

Swanley Village, the original settlement that took that name in the 1920s, has older homes with a more rural feel, and Hockenden and Crockenhill form part of the wider urban area. Across all of them, hardened uPVC window mastic is one of the most common outside jobs.

Flats, maisonettes and homes next to the motorway

In blocks of flats, a failed shower seal rarely stays your own problem. Water finds its way through the floor and shows as a stain on the ceiling below, and by then the joint has usually been leaking for weeks. We can work with housing associations, managing agents and residents on access, and bring everything up in one trip.

Being right on the M25, A20 and M20 junction, Swanley sees a lot of traffic, and window frames close to busy roads gather dust and grime that sticks to old, tacky mastic. When we replace external joints, we clean the frame and surrounding brick thoroughly before applying a flexible window and door mastic, so the new sealant bonds to sound, clean surfaces.

The Swanley Centre, landlords and local businesses

The Swanley Centre, with its Asda supermarket, shops and offices, is the focus of the town’s retail. Customer toilets, staff washrooms and food areas in shops, cafés and offices all need sound, clean sealant, and out-of-hours working can be arranged so they are not out of use during the day.

We also reseal for landlords and letting agents across the town, between tenancies or after a tenant reports mould, and can quote for several properties together.

How it works

  1. Call or email. Tell us what needs doing, where it is and anything about access. Photos by email help.
  2. Quote and booking. We quote clearly before anything starts and fix a day that works for you.
  3. Strip back the old joint. Every bit of old sealant is removed and the joint is cleaned, treated for mould and dried.
  4. Seal and finish. The right sealant for each joint is applied and tooled to a neat, even finish.
  5. Cure and guarantee. We tell you when it can be used, and every job has our one-year guarantee.

Questions from Swanley

Do you cover all of Swanley?

Yes. We cover the town centre, St Mary’s, White Oak, Swanley Village, Hockenden and Crockenhill, and Hextable nearby.

My bath has several layers of old silicone. Can you sort it?

Yes. We remove every layer back to clean surfaces before applying a single new bead. New silicone won’t bond properly to old.

Do you work for housing associations?

Yes. We can work with housing associations and managing agents and arrange access to flats and communal areas.

There’s a stain on my ceiling from the flat above. Could it be the shower?

Often it is a failed tray or screen seal upstairs. We can reseal it, though a leaking pipe needs a plumber first.

Can you reseal a shop toilet before we open?

Out-of-hours working can be arranged for commercial jobs, so customer and staff toilets are ready again before the doors open.

My kitchen worktop joint has gone black by the sink. Can that be replaced?

Yes. We cut out the old sealant, clean and dry the joint and use a colour-matched silicone, with a food-safe product where it meets the sink.

Can you match the sealant to coloured tiles or a grey worktop?

Yes. We carry a range of colours and can match most tiles, trays and worktops, so the new joint blends in rather than standing out.

Is the work guaranteed?

Yes. Every job has our one-year guarantee.
