About our remedial sealant in Newhaven

With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We work on expansion joints, shrunken worktop sealant and leaking tray & enclosure joints, and the jobs we see most are sealant peeling off a dusty or damp surface and black mould underneath the bead.

Stone-built tenements are part of every Scottish city, alongside houses and newer flats. With flats above and below, a leak from a tired seal can reach the flat underneath.

Our work is backed for twelve months.

Bathrooms and kitchens in Newhaven

Newhaven is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. There are hotels and other places to stay in and around Newhaven. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

Rented homes near Edinburgh Waverley station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Trinity Academy? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Common problems we fix in Newhaven

Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.

These are the problems we’re asked about most:

  • Mould trapped under a layer of silicone
  • Products that weren’t meant for the joint
  • Sealant peeling off a dusty or damp surface
  • Over-sealed joints coming away

For an older house near a landmark such as Newhaven Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant.

What affects the quote in Newhaven

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

  • How many rooms, windows or areas are involved
  • The size of the job
  • Any mould that needs treating
  • The old material and how stubborn it is

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Asking for a quote

What to tell us when you ask for a quote:

  • What’s wrong with the joints now
  • Whether it’s a home or a business
  • Roughly how big the job is
  • Where the property is

Need a quote? Please drop us a line at info@mrmastic.co.uk with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

The process

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours, depending on how many layers have to come out, depending on the amount of work. Parking in city streets around Newhaven can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.

  1. Surrounding tiles, trays and frames are protected first.
  2. Every layer of failed sealant is stripped out.
  3. The joint is degreased and checked for movement and leaks.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

Getting ready for the visit

  • Move anything stored near the joints
  • Mention any parking rules near the property
  • Mention any leaks or damp you’ve noticed

Getting a quote

Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.

Advice

Newhaven questions

I’m in a tenement in Newhaven. Could worn sealant affect the flat downstairs?

Yes, and the first sign is often a mark on the ceiling below. A proper reseal, with all the old sealant cut out, stops it at the source.

Do you work for hotels and guest houses in Newhaven?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

Are you an approved applicator?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Does remedial work come with a guarantee?

Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.

Can you match the sealant colour?

Generally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.

Someone resealed my shower and it’s leaking again. Can you help?

Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Landlords, agents and businesses in Newhaven

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

When something else is needed

We’d rather tell you now than do work that will not last, so these are the limits:

  • Water damage behind tiles that needs a tiler
  • A tray or worktop that needs refixing first
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

What we seal

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

Leave it or put it right?

A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. In a tenement flat in Newhaven, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

What you get with us

  • A 12-month guarantee on all work
  • You choose the colour before work begins
  • Over 20 years’ experience
  • We leave the area clean and tidy
