Trusted remedial sealant in Peckham

Remedial sealant for homes and businesses in Peckham

A joint that keeps failing usually has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints, and the jobs we see most are decorators’ caulk around a bath or shower and over-sealed joints coming away.

London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Peckham, remedial sealant is as much about a room looking cared for as about keeping water out.

All our work is covered by a 12-month guarantee, wherever you are in Greater London.

When to call us in Peckham

How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing sets the depth and stops that.

These are the problems we are asked about most:

  • Sealant applied over old sealant that has lifted
  • Dark patches showing through the sealant
  • Repeat leaks from the same joint
  • Kitchen joints letting water behind the worktop

Peckham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

10 questions to ask before you book

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Remedial sealant around Peckham

Peckham has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.

For site and facilities teams at buildings such as John Donne Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For an older house near a landmark such as All Saints Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Landlords, agents and businesses in Peckham

Landlords and letting agents in Peckham can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

What affects the quote in Peckham

Your quote is based on your job. We look at:

  • The number of rooms or windows
  • Access and height
  • The type of sealant required
  • Mould in or behind the old joints

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

What to tell us when you ask for a quote:

  • Roughly how big the job is
  • The type of property
  • A few pictures by email, if you can
  • Any previous sealing or DIY work

We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job.

Honest limits

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • A tray or bath that is cracked
  • Failed tanking or loose tiles behind the sealant
  • Sealant in an older building that needs testing for asbestos first

If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Surfaces we seal

  • Mouldy bath & shower sealant
  • Expansion joints
  • Failed movement joints
  • Leaking tray & enclosure joints
  • Botched or over-sealed joints
  • Shrunken worktop sealant

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  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. The right product goes in, with backing where the joint moves.
  5. The joint is tooled and you are told about anything else we found.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Let us know about stairs, lifts or work at height
  • On commercial sites, let us know about site rules

Related advice

Leave it or put it right?

Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Questions from Peckham

Can worn sealant in a flat in Peckham cause a leak downstairs?

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

Do you work in hotels near Peckham?

Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

What does remedial sealant cost?

Someone resealed my shower and it’s leaking again. Can you help?

Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Mr Mastic is based in Crawley. We cover Peckham and the rest of Greater London.

How long before the joint can be used?

It depends on the product and the conditions. We tell you how long to leave it before we go.
