Remedial sealant in Pimlico

About our remedial sealant in Pimlico

Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. Common call-outs are for floor or wall movement joints that have failed and sealant peeling off a dusty or damp surface, across leaking tray & enclosure joints, failed movement joints and expansion joints.

Being in a small place like Pimlico 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.

Our work is backed for twelve months, in Pimlico and everywhere else we cover.

Pimlico: your questions answered

Is Pimlico within the area you cover?

Yes. Pimlico is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Kings Langley station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.

What if resealing won’t fix my leak?

You’ll hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.

Can I choose the sealant colour?

We will suggest a colour to suit the surroundings. The product needed can limit the range.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Do you work for hotels and businesses?

Yes. We’ve worked for hotels, offices and other businesses.

How long before the joint can be used?

Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.

Do I have to be there?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.

Quotes for remedial sealant in Pimlico

We quote each job individually. These are the things that affect it:

  • How much there is to do
  • Working hours on commercial sites
  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

To help us quote quickly, let us know:

  • The type of property
  • Photos by email, if that is easy
  • If someone has resealed it before
  • The rough size of the job

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or send us an email.

What happens on the day

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Pimlico needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Surrounding tiles, trays and frames are protected first.
  2. The botched or failed sealant is cut away completely.
  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.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height

Getting a quote

We quote each job on its own. Simply call 0345 464 0079 or email us and describe the job and send pictures if you have them.

Related advice

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

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.

Pimlico homes and their sealant

Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.

Schools such as Bedmond Academy are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of the Ascension include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Landlord and commercial work in Pimlico

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Different surfaces, different methods

Worktops & kitchens

A loose worktop splits its sealant. That needs refixing before resealing, which we will point out.

Movement & expansion joints

Bonding on three sides is a common reason movement joints tear. Backing stops that, so the sealant grips the two sides only.

Common problems we fix in Pimlico

Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.

Most people get in touch after spotting something like this:

  • Sealant that came away because the surface wasn’t prepared
  • Dark patches showing through the sealant
  • Sealant applied over old sealant that has lifted
  • A shower that leaks however often it’s resealed

Rented homes near Kings Langley station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Questions to ask before you book

  • Whether VAT is included
  • What the cure time is
  • What happens if the job turns out different
  • Whether all the old sealant comes out first

How to choose a mastic man

Why it’s worth doing now in Pimlico

Ripping out a bathroom is not normally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Older cottages and farmhouses around Pimlico can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
