Remedial sealant for Turnpike Lane homes and businesses

How the job changes by surface

Over-sealed & botched joints

A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.

Windows & doors

Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.

Remedial sealant in Turnpike Lane

A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are black mould underneath the bead and decorators’ caulk around a bath or shower.

Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Turnpike Lane more than a cosmetic job.

Every job is covered by a one-year guarantee, wherever you are in Greater London.

Common problems we fix in Turnpike Lane

Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.

Most people get in touch after spotting one of these:

  • Movement joints that have split or pulled away
  • Mould trapped under a layer of silicone
  • Worktop sealant that has shrunk and split
  • A shower that leaks however often it’s resealed

Turnpike Lane is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Questions to ask before booking

  • What guarantee comes with the work
  • What happens if they find a problem under the old sealant
  • How the surfaces are prepared before sealing
  • Whether you can choose the colour

Choosing a sealant specialist

Why deal with it now?

Ripping out a bathroom is not usually needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we will tell you. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Why book with us

How to look after the new joints

To keep the joints looking good and working properly:

  • Keep bleach and abrasives off the bead
  • Keep an eye on the ceiling below the bathroom
  • Never fill a movement joint with mortar or grout
  • Get the cause of a repeat leak found before resealing

Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just call 0345 464 0079 or send us an email.

A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

How it works

The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Turnpike Lane. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. Mould is treated and the joint dried.
  4. We reseal with a product suited to the joint, backed where needed.
  5. The joint is tooled and you are told about anything else we found.

Before we arrive

  • Clear the area around the work
  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Turnpike Lane questions

Do you work in hotels near Turnpike Lane?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

I live in a flat in Turnpike Lane. Can a failed seal leak into the flat below?

Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Can you fix a reseal that hasn’t worked?

Yes. There’s usually a reason: sealant over sealant, movement or another leak, so we find that first.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Can failed expansion joints be resealed?

Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

For landlords and businesses

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Bathrooms and kitchens in Turnpike Lane

In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. There are hotels and other places to stay in and around Turnpike Lane. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

Managing a site like North Harringay Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. If you live in an older home near Church of St John The Baptist (greek Orthodox), bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
