What remedial sealant looks like in Bulstrode

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.

If you let a flat or house near Hemel Hempstead station, a joint that keeps failing is best fixed properly while the property is empty. If you look after a building such as Bovingdon Primary Academy, 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.

How we handle remedial sealant in Bulstrode

Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you have floor or wall movement joints that have failed and sealant that came away because the surface wasn’t prepared, we can help, on shrunken worktop sealant, failed movement joints and botched or over-sealed joints alike.

Being in a small place like Bulstrode makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

When something else is needed

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

  • Sealant in an older building that needs testing for asbestos first
  • A bath, tray or worktop that moves until it’s properly fixed
  • Cracks in the fitting rather than the joint

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

Where we work in Bulstrode

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

Surface by surface

Movement & expansion joints

Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal.

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.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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.

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Common questions in Bulstrode

Will you come out to Bulstrode?

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.

I let a flat near Hemel Hempstead station. Can you help?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

What should I tell you?

A short description and the location, with pictures by email if possible. We will ask anything else we need to know.

Can failed expansion joints be resealed?

Yes. The depth is set with backing so the sealant only bonds to the two sides.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

Do you guarantee remedial jobs?

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

Where are you based?

Mr Mastic is based in Crawley. We cover Bulstrode and the rest of Hertfordshire.

When to call us in Bulstrode

Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.

If you can see any of these, it’s time to have the joints looked at:

  • Torn expansion joints
  • Repeat leaks from the same joint
  • Sealant applied over old sealant that has lifted
  • Gaps opening along the back of the worktop

If you live in an older home near Church of St Lawrence, older homes can move a little, which is hard on rigid grout and tired sealant.

Before you book anyone

  • Whether VAT is included
  • Whether they’re fully insured
  • What happens if they find a problem under the old sealant
  • How the joint is cleaned and prepared

Our hiring checklist

Why it’s worth doing now in Bulstrode

Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Around Bulstrode, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

The process

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Bulstrode, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we find out how and where the joint has failed.
  2. Every layer of old sealant is cut and cleaned out.
  3. The joint is cleaned, treated for mould and left to dry.
  4. We use the right backing and sealant for any joint that moves.
  5. The new joint is tooled neatly and we explain anything else we found.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children
