Remedial sealant in North End, done properly

Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. We work on mouldy bath & shower sealant, botched or over-sealed joints and leaking tray & enclosure joints, and common reasons people get in touch are kitchen joints letting water behind the worktop and caulk or the wrong sealant used in a wet area.

Around North End, you will mostly find houses and bungalows, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.

Whatever the size of the job, you get the same 12-month guarantee in North End and across Portsmouth.

What happens on the day

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. For a job in North End, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We look at how the sealant has failed and check for movement or a leak path.
  2. Every layer of old sealant is cut and cleaned out.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. The new joint is tooled neatly and we explain anything else we found.

How to prepare

  • Mention if the joints have been sealed before
  • Clear the area around the work
  • Keep pets and children clear of the area while we work

Advice

How we quote for remedial sealant

Jobs vary more than people expect. The main factors:

  • The old material and how stubborn it is
  • The number and length of the joints
  • Whether there’s mould to deal with
  • The number of rooms or windows

Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What we need to know

To make quoting easier, let us know:

  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • If someone has resealed it before
  • How we’d reach the joints

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

Why act early in North End

DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Homes in smaller places like North End can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What you get with us

  • Experience in homes, commercial sites and hotels
  • Quality sealants from Arbo and Everbuild
  • Anti-fungal sanitary silicone in wet areas
  • White, clear, grey or another colour, product permitting

Questions from North End

Can you do remedial sealant in North End?

Yes, North End is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

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

Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do you offer different sealant colours?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you work on commercial sites?

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

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

Allow a few hours, depending on how many layers have to come out. You’ll know the timing when we quote.

Can you reseal a split movement joint?

Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

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, and the work is guaranteed for a year.

When something else is needed

We’ll always be straight with you, so here’s what sealant cannot fix:

  • A cracked shower tray or bath (that needs repair or replacing)
  • Sealant in an older building that needs testing for asbestos first
  • Movement from fittings that aren’t supported

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • Expansion joints
  • Leaking tray & enclosure joints
  • Botched or over-sealed joints

Landlord and commercial work in North End

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

When to call us in North End

Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.

Signs it’s time to call us include:

  • Decorators’ caulk around a bath or shower
  • Smears and lumps from a botched reseal
  • Dark patches showing through the sealant
  • Gaps opening along the back of the worktop

Managing a site like Corpus Christi Catholic Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What to look for in a quote

  • How long the guarantee is
  • Whether VAT is included
  • Whether you can choose the colour
  • Whether the sealant suits the joint

Choosing a sealant specialist

Remedial sealant in North End: local notes

North End is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.

For landlords with property near Hilsea station, botched sealant from a previous quick fix is easier to strip out between tenants. In the older streets around St. Mark’s, older homes can move a little, which is hard on rigid grout and tired sealant.

North End is about 1 mile north of Portsmouth, in Portsmouth. Across the PO2 area, we can carry out remedial sealant at your property. Our area takes in 19 places across Portsmouth, large and small.
