Remedial sealant near Longworth

Common problems we fix in Longworth

How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

Any of these means the joints need attention:

  • A second bead peeling off the first
  • Decorators’ caulk around a bath or shower
  • Black mould underneath the bead
  • Torn expansion joints

If you live in an older home near Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Choosing a sealant specialist

Remedial sealant for homes and businesses in Longworth

Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on expansion joints, leaking tray & enclosure joints and shrunken worktop sealant, and people most often call us about movement joints that have split or pulled away and thick, messy sealant smeared over tiles.

Being in a small place like Longworth makes no difference to the job itself: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.

The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What the job involves on each surface

Leaking trays & enclosures

Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.

What remedial sealant looks like in Longworth

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

If you look after a building such as Longworth Primary School, 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.

For landlords and businesses

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Why deal with it now?

A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you’ll hear it from us. Where a wall is exposed, as many are in small places like Longworth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

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.

Why us?

  • You choose the colour before work begins
  • Sealant colour chosen to suit
  • Experience in homes, commercial sites and hotels
  • A 12-month guarantee on all work

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

What affects the cost of remedial sealant

The quote reflects the job in front of us. We look at:

  • When we can work, for business premises
  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • Any mould that needs treating

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What we need to know

Before you ask for a quote, have a think about:

  • Where the property is
  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • Whether it has been sealed before

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

How the visit works

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours, depending on how many layers have to come out. In a small place like Longworth, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Surrounding tiles, trays and frames are protected first.
  2. Every layer of failed sealant is stripped out.
  3. The joint is degreased and checked for movement and leaks.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

Before we arrive

  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before
