Signs you need remedial sealant in Whitchurch

Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.

Look out for any of the following:

  • Thick, messy sealant smeared over tiles
  • Caulk or the wrong sealant used in a wet area
  • Worktop sealant that has shrunk and split
  • Torn expansion joints

For site and facilities teams at buildings such as Whitchurch Church of England 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.

About our remedial sealant in Whitchurch

Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We work on failed movement joints, expansion joints and botched or over-sealed joints, and the jobs we see most are sealant applied over old sealant that has lifted and caulk or the wrong sealant used in a wet area.

Around Whitchurch, you’ll mostly find houses and bungalows, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.

Big or small, it’s backed by our one-year guarantee in Whitchurch and across Hampshire.

How to look after the new joints

To keep the joints looking good and working properly:

  • Act on a lifting corner right away
  • Don’t point over movement joints
  • Get the cause of a repeat leak found before resealing
  • Check ceilings under showers for marks

If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.

A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.

What sealant work can’t fix

It helps to know what we cannot do:

  • Movement from fittings that are not supported
  • Failed tanking or loose tiles behind the sealant
  • Plumbing leaks behind walls or under trays

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

Surfaces we seal

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

Quotes for remedial sealant in Whitchurch

Every job gets its own quote. This is what makes a difference:

  • The number of rooms or windows
  • The size of the job
  • Any working-time requirements on site
  • Whether old sealant or filler has to be cut out

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

What to tell us for a quote

To make quoting easier, let us know:

  • The rough size of the job
  • The address or postcode of the job
  • Whether it has been sealed before
  • How we’d reach the joints

Different surfaces, different methods

Mouldy bath & shower sealant

Where mould keeps coming back, ventilation is normally part of the cause. We will reseal and tell you if extraction looks to be the issue.

Movement & expansion joints

A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.

Whitchurch questions

I let a flat near Whitchurch (Hampshire) station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Can you do remedial sealant in Whitchurch?

Yes, Whitchurch is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Can you fix a reseal that hasn’t worked?

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

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

Can you match the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

Is it messy?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us.

What if the leak is not the sealant?

We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. A visit to Whitchurch is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We protect the surfaces around the joint.
  2. The botched or failed sealant is cut away completely.
  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. We give you the cure time and explain what caused the failure.

How to prepare

  • Tell us if parking is tricky
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
