Remedial sealant for Harestock homes and businesses

Can I do it myself?

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

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

About our remedial sealant in Harestock

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. New sealant only bonds to a clean, dry joint. If you are dealing with black mould underneath the bead and beads that never stuck properly, we can help, whatever the surface.

Homes around Harestock range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.

All of our work is guaranteed for twelve months, in Harestock and everywhere else we cover.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • A tray or worktop that needs refixing first
  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Where we work in Harestock

What affects the cost of remedial sealant

  • The product the joint needs
  • The size of the job
  • How much old sealant there is and how hard it is to remove
  • How many areas need sealing

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

Helping us quote

There’s no need for technical detail. Just tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved
  • If someone has resealed it before
  • The type of property

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or drop us an email.

Different surfaces, different methods

Leaking trays & enclosures

Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.

Remedial sealant around Harestock

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

If you live in an older home near Saint Barnabas, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as Harestock Primary School are buildings too, and 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.

What we are called out for in Harestock

Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.

Most people get in touch when they notice one of these:

  • Black mould underneath the bead
  • Gaps opening along the back of the worktop
  • Floor or wall movement joints that have failed
  • A second bead peeling off the first

Rented homes near Winchester station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

What to look for in a quote

  • Whether they seal over old material or remove it
  • What the quote includes, VAT included or not
  • Whether the sealant suits the joint
  • How much experience the applicator has

How the visit works

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. In a smaller place like Harestock, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. We strip the joint completely, removing any layers below.
  3. Next, any mould is treated and the joint dried.
  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.

Getting ready for the visit

  • Mention any parking rules near the property
  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive

Leave it or put it right?

Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In an older home around Harestock, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
