Remedial sealant in Cookham

Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and remedial work carries our one-year guarantee. Common call-outs are for sealant applied over old sealant that has lifted and smears and lumps from a botched reseal, on failed movement joints, shrunken worktop sealant and mouldy bath & shower sealant.

In a smaller place like Cookham, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.

We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Signs you need remedial sealant in Cookham

Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.

People usually contact us after spotting one of these:

  • Smears and lumps from a botched reseal
  • Caulk or the wrong sealant used in a wet area
  • Dark patches showing through the sealant
  • Sealant applied over old sealant that has lifted

Letting a property close to Cookham station? Then a joint that keeps failing is best fixed properly while the property is empty.

What your quote should include

  • How much experience the applicator has
  • Whether they’re fully insured
  • The length of the guarantee
  • Whether the sealant suits the joint

10 questions to ask before you book

How it works

We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. In a smaller place like Cookham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. We protect the surfaces around the joint.
  2. Every layer of failed sealant is stripped out.
  3. The joint is degreased and checked for movement and leaks.
  4. New sealant goes in once the joint is dry, and is tooled smooth.
  5. You get the cure time and our view on why the joint failed.

How to prepare

  • Keep pets and children clear of the area while we work
  • For business premises, tell us about site rules or sign-in
  • Let us know about earlier repairs to the joints

What affects the quote in Cookham

Call for a quick quote. The main things that affect it are:

  • Whether there’s mould to deal with
  • How many areas need sealing
  • The product the joint needs
  • Any working-time requirements on site

Rather than a set price list, 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.

Helping us quote

You do not need to know the technical terms. Just tell us:

  • How many joints, rooms or windows are involved
  • The type of property
  • The address or postcode of the job
  • Photos by email, if that is easy

For remedial sealant in Cookham, ring 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Get the cause of a repeat leak found before resealing
  • Deal with small splits early
  • Keep movement joints clear of mortar and paint
  • Clean sealant with mild products only

Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.

Do not keep resealing the same joint. Have someone find out why, or the next bead will go the same way.

When something else is needed

To be straight with you, there are a few things sealant will not fix:

  • Tiles that have come away from the wall
  • A leaking trap, valve or supply pipe
  • Movement from fittings that are not supported

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Where we work in Cookham

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

Remedial sealant around Cookham

Cookham 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. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

Managing a site like Cookham Rise Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St John the Baptist, walls and floors in older homes can move, and sealant and grout show it first.

Different surfaces, different methods

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.

Windows & doors

Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.

What happens if it’s left?

A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a smaller place like Cookham, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Why book with us

  • Full insurance on every job
  • White, clear, grey or another colour, product permitting
  • Trusted Arbo and Everbuild sealants
  • A 12-month guarantee on all work

Common questions in Cookham

Do you work for hotels and guest houses in Cookham?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

I let a flat near Cookham station. Can you help?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.

Will the old sealant be removed?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Where do you work from?

We work from Crawley. Our applicators cover Cookham.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done and we’ll quote it together.

What if resealing won’t fix my leak?

We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we won’t pretend it will.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.

Are you insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
