Remedial sealant in California

A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you are dealing with sealant that came away because the surface wasn’t prepared and kitchen joints letting water behind the worktop, we can put it right, on leaking tray & enclosure joints, failed movement joints and expansion joints alike.

Even in a smaller place like California, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.

Whatever the size of the job, it’s backed by our 12-month guarantee in California and across Buckinghamshire.

When to call us in California

Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.

Most people get in touch after spotting one of these:

  • Sealant applied over old sealant that has lifted
  • Repeat leaks from the same joint
  • Sealant that came away because the surface wasn’t prepared
  • Thick, messy sealant smeared over tiles

If you let a flat or house near Aylesbury station, a joint that keeps failing is best fixed properly while the property is empty.

Questions to ask before you book

  • Who does the work, and how experienced they are
  • How the surfaces are prepared before sealing
  • Whether you can choose the colour
  • Is VAT in the price?

Our hiring checklist

Looking after it afterwards

Looking after new joints is easy:

  • Keep bleach and abrasives off the bead
  • Air the bathroom so the sealant can dry
  • Don’t add new sealant on top of old
  • Deal with small splits early

Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or email us.

Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Landlords, agents and businesses in California

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Common questions in California

Will you come out to California?

Yes. California is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you help a landlord with a rental near Aylesbury station?

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

How long will it take to strip and reseal the joint?

A little longer than a standard reseal. For most joints, it’s a few hours.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

What does remedial sealant cost?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Do you have insurance?

Yes, we are fully insured.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.

Different surfaces, different methods

Leaking trays & enclosures

If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We will tell you what we find.

Windows & doors

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

California homes and their sealant

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. There are hotels and other places to stay in and around California. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

Homes close to Church of St Mary include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Oak Green School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How we quote for remedial sealant

Your quote is based on your job. We take into account:

  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • How many areas need sealing

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

Helping us quote

When you contact us, it’s useful to know:

  • What’s wrong with the joints now
  • Whether it has been sealed before
  • The address or postcode of the job
  • Whether it’s a home or a business

Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

When something else is needed

It helps to know what we cannot do too:

  • A cracked shower tray or bath (that needs repair or replacing)
  • Failed tanking or loose tiles behind the sealant
  • Movement from fittings that are not supported

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

Joints and surfaces we work on

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

What we do, step by step

At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the amount of work. In a smaller place like California, 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. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. Finally we finish the joint and talk you through what we found.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive
