What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. Somewhere as small as Denchworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we find out how and where the joint has failed.
  2. Every layer of old sealant is cut and cleaned out.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. We tool the joint and tell you about anything else that needs attention.

How to prepare

  • Mention any parking rules near the property
  • Let us know if you’ve seen damp or leaks
  • Keep pets and children clear of the area while we work

How we handle remedial sealant in Denchworth

Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. We work on leaking tray & enclosure joints, botched or over-sealed joints and mouldy bath & shower sealant, and people most often call us about products that weren’t meant for the joint and torn expansion joints.

Homes around Denchworth are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.

Whatever the size of the job, it’s backed by our one-year guarantee.

What affects the cost of remedial sealant

The price is agreed before any work begins. It’s based on:

  • The product the joint needs
  • Working hours on commercial sites
  • The number of rooms or windows
  • Mould in or behind the old joints

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • Any access issues, like height or stairs
  • Photos by email, if that is easy
  • Whether it has been sealed before
  • Whether it’s a home or a business

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.

How the job changes by surface

Mouldy bath & shower sealant

Black mould inside the bead will not scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.

Worktops & kitchens

Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed in a colour to suit.

Why deal with it now?

DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. In a small place like Denchworth, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Why book with us

  • Quality sealants from Arbo and Everbuild
  • A choice of colours where the product allows
  • A sealant colour to suit the surroundings
  • Old sealant always removed completely

What remedial sealant looks like in Denchworth

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you live in an older home near Church of St James, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Signs you need remedial sealant in Denchworth

Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.

It’s worth asking for a quote if you see:

  • Black mould underneath the bead
  • Decorators’ caulk around a bath or shower
  • Beads that never stuck properly
  • A shower that leaks however often it’s resealed

In and around Denchworth, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

10 questions to ask before you book

For landlords and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Can I do it myself?

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.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
