Remedial sealant for Basingstoke homes and businesses

The process

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most joints, depending on how much old sealant has to come out. For homes and businesses in busier parts of Basingstoke, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.

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

Preparing for the visit

  • Tell us if parking is tricky
  • Try not to wet indoor joints just before the visit
  • Mention any leaks or damp you’ve noticed

Remedial sealant in Basingstoke

Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have torn expansion joints and wide, uneven beads that look worse than the old ones, we can put it right, on leaking tray & enclosure joints, shrunken worktop sealant and expansion joints alike.

Basingstoke has offices, shops and other businesses as well as homes, all with washrooms and kitchens that need the same care as a family bathroom. Homes and businesses get the same careful preparation before anything new goes in.

All our work is covered by a 12-month guarantee, wherever you are in Hampshire.

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • Failed tanking or loose tiles behind the sealant
  • A tray or bath that’s cracked
  • Older mastics that may need an asbestos check before removal

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Joints and surfaces we work on

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

Bathrooms and kitchens in Basingstoke

Basingstoke has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Most of the South East has hard water, 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 St Michael's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as King's Furlong Infant School and Nursery, we reseal washrooms and kitchens in schools and businesses as well as homes. For landlords with property near Basingstoke station, botched sealant from a previous quick fix is easier to strip out between tenants.

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Find out why the sealant failed first
  • Deal with small splits early
  • Check ceilings under showers for marks
  • Keep bleach and abrasives off the bead

Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.

A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too in Basingstoke and across Hampshire. We can quote a run of properties together.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

How we quote for remedial sealant

There’s no set price list, because no two jobs are the same. The quote depends on:

  • The number and length of the joints
  • Working hours on commercial sites
  • Access and height
  • The product the joint needs

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Helping us quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Where the job is, and your postcode
  • The rough size of the job
  • Whether it’s a home or a business
  • Photos by email, if that’s easy

For remedial sealant in Basingstoke, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

Why deal with it now?

Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. In a busy place like Basingstoke, a failed joint in a flat or office can send water into the space below, where it’s often found late and is bigger to put right.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Why us?

  • White, clear, grey or coloured to suit, where the product allows
  • Over 20 years’ experience
  • Anti-fungal silicone where joints get wet
  • Colour picked to suit the job

Questions from Basingstoke

I let a flat near Basingstoke station. Can you help?

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’ll give you a clear quote.

Do you take on hotel work around Basingstoke?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Can you remove sealant that’s been put over old sealant?

Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.

Are you fully insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

How long does remedial resealing take?

That depends on how many layers there are and how many joints. We will tell you before any work starts.

What if the leak isn’t the sealant?

Then we explain what we have found. A plumber or fitter may be needed before any new sealant goes on.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
