Remedial sealant near Lower Upham

What we are called out for in Lower Upham

One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.

It’s worth asking for a quote if you see:

  • Sealant that came away because the surface wasn’t prepared
  • Decorators’ caulk around a bath or shower
  • Black mould underneath the bead
  • Sealant applied over old sealant that has lifted

Managing a site like Upham Church of England Aided Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What your quote should include

  • Is VAT in the price?
  • Which sealant they’ll use, and why
  • What happens if they find a problem under the old sealant
  • Whether they’re fully insured

About our remedial sealant in Lower Upham

Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We are often asked to deal with torn expansion joints and caulk or the wrong sealant used in a wet area, on expansion joints, mouldy bath & shower sealant and shrunken worktop sealant.

Homes around Lower Upham are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.

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

What remedial sealant looks like in Lower Upham

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

In the older streets around Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Hedge End station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What sealant work cannot fix

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • A bath, tray or worktop that moves until it’s properly fixed
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • Water damage behind tiles that needs a tiler

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

Surfaces we seal

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

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Keep the room well ventilated
  • Use a soft cloth, not a scourer, on silicone
  • Have loose fittings fixed before resealing
  • Always have old sealant cut out, not covered

Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.

Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.

Quotes for remedial sealant in Lower Upham

The price is agreed before any work begins. It takes into account:

  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove
  • The amount of work
  • How many areas need sealing

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Access, such as stairs, a lift or height
  • Where the job is, and your postcode
  • Roughly how big the job is
  • Whether it’s a home or a business

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Questions from Lower Upham

Will you come out to Lower Upham?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Lower Upham in your area for remedial sealant?

Yes, Lower Upham is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.

What information do you need?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.

Do you guarantee remedial jobs?

Yes. Every job comes with our 12-month guarantee.

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

That depends on how many layers there are and how many joints. We’ll tell you before we start.

Different surfaces, different methods

Mouldy bath & shower sealant

Where mould keeps coming back, ventilation is usually part of the cause. We will reseal and tell you if extraction looks to be the issue.

Windows & doors

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

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Lower Upham, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. The joint is tooled and you are told about anything else we found.

Getting ready for the visit

  • Mention any tricky access
  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children
