Remedial sealant for Aston homes and businesses

What we are called out for in Aston

A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.

These are the problems we are asked about most:

  • Sealant applied over old sealant that has lifted
  • Caulk or the wrong sealant used in a wet area
  • Dark patches showing through the sealant
  • Worktop sealant that has shrunk and split

If you let a flat or house near Knebworth station, botched sealant from a previous quick fix is easier to strip out between tenants.

Remedial sealant for homes and businesses in Aston

Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. If you’re dealing with over-sealed joints coming away and repeat leaks from the same joint, we can put it right, whatever the surface.

Around Aston, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.

You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What remedial sealant looks like in Aston

Aston is part of Stevenage, one of the post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. Sealant laid over old sealant never bonds properly, so it all has to come out. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

For an older house near a landmark such as Parish Church of St Mary the Virgin, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Schools such as Aston St Mary's Church of England Aided Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Aston is about 2 miles south-east of Stevenage, in Hertfordshire.

What happens on the day

The work is kept neat and contained to the area we are working on. The job normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like Aston 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. Every layer of failed sealant is stripped out.
  3. We clean and degrease the joint and look for signs of movement or water.
  4. New sealant goes in once the joint is dry, and is tooled smooth.
  5. You get the cure time and our view on why the joint failed.

Preparing for the visit

  • Tell us if parking is tricky
  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children

Related advice

Work for landlords, hotels and businesses

Letting agents and landlords in Aston can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

Aftercare tips

After the cure time, these simple habits help:

  • Keep the room well ventilated
  • Act on a lifting corner straight away
  • Check trays and worktops do not move
  • Clean sealant with mild products only

Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or drop us an email.

Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.

Aston: your questions answered

Do you cover smaller places like Aston?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is it worth replacing old sealant in an older home in Aston?

If it hasn’t been replaced for some years, it’s generally worth it. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather.

Can you quote for more than one area?

Yes. Just list everything you need.

Can you remove sealant that is been put over old sealant?

Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Do you offer different sealant colours?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Do you do commercial work?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’re 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.

Why act early in Aston

Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Around Aston, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
