About remedial sealant in Hampshire

If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you ring 0345 464 0079 or drop us an email, and say how long ago it was last done. Typical jobs include decorators’ caulk around a bath or shower and mould trapped under a layer of silicone, on leaking tray & enclosure joints, shrunken worktop sealant and failed movement joints.

On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on how many layers have to come out.

We look at how the sealant has failed and check for movement or a leak path.
All the old sealant comes out, including any layers underneath.
We clean the joint, treat any mould and let it dry.
We use the right backing and sealant for any joint that moves.
The new joint is tooled neatly and we explain anything else we found.

How we quote

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Remedial sealant across Hampshire: local notes

From Basingstoke, Winchester and Gosport to its smaller places, homes across Hampshire have bathrooms and kitchens of every age. Family bathrooms, rented flats and hotel en suites all need their sealant and grout renewing in time.

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Whatever the job in Hampshire, surfaces are cleaned back properly before new sealant goes in. Along the coast in Hampshire, holiday lets and guest houses can have bathrooms in near-constant use, which is hard on sealant and grout.

Basingstoke: In the older streets around St Michael's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For site and facilities teams at buildings such as King's Furlong Infant School and Nursery, 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.

Surface by surface

Windows & doors

A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.

Worktops & kitchens

A loose worktop splits its sealant. It needs fixing down first, and we will tell you if we find it.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

A leaking trap, valve or supply pipe
A bath, tray or worktop that moves until it’s properly fixed
Cracks in the fitting rather than the joint

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 does not work out, we can still put it right.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What affects the quote in Hampshire

You’ll get a clear quote before any work starts. It takes into account:

The number and length of the joints
Whether old sealant or filler has to be cut out
The number of rooms or windows
Mould in or behind the old joints

Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

A few pictures by email, if you can
Roughly how big the job is
Any previous sealing or DIY work
The type of property

Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.

What we are called out for in Hampshire

Joint depth matters. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

If you can see any of these, it’s time to have the joints looked at:

Sealant peeling off a dusty or damp surface
Sealant applied over old sealant that has lifted
Caulk or the wrong sealant used in a wet area
Movement joints that have split or pulled away

Your questions about remedial sealant in Hampshire

How long does the work take?

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

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few pictures.

How long before the joint can be used?

It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.

Do you take out the old sealant first?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Will there be a smell?

There can be a smell while the sealant cures. Ventilation helps.

I’m a tenant. Can you help?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
