Remedial sealant in Mill End

Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. If you have mould trapped under a layer of silicone and torn expansion joints, we can put it right, whatever the surface.

In a smaller place like Mill End, homes are mostly houses and bungalows rather than flats, some older and some much newer. Sealant and grout wear out here just as they do in a big town.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What we’re called out for in Mill End

Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.

These are the problems we’re asked about most:

  • Dark patches showing through the sealant
  • Beads that never stuck properly
  • Wide, uneven beads that look worse than the old ones
  • Gaps opening along the back of the worktop

If you live in an older home near Church of St Peter, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What your quote should include

  • Are they insured?
  • When the joint can take water or movement
  • What happens if the job turns out different
  • Which sealant they’ll use, and why

Our hiring checklist

How the visit works

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material 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 Mill End, 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. Every layer of old sealant is cut and cleaned out.
  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. Finally we finish the joint and talk you through what we found.

How to prepare

  • Clear items away from the joints we are working on
  • On commercial sites, let us know about site rules
  • Tell us about any water getting in

Different surfaces, different methods

Leaking trays & enclosures

If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.

Mouldy bath & shower sealant

Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

If you manage several properties in or around Mill End, several properties can be quoted together. Just tell us the addresses and what each one needs.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out 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 fails, we can still redo it.

When it isn’t the sealant

In fairness, there are a few things sealant will not fix:

  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • A bath, tray or worktop that moves until it’s properly fixed
  • Failed tanking or loose tiles behind the sealant

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Where we work in Mill End

What affects the cost of remedial sealant

The price is agreed before any work begins. It’s based on:

  • How much there is to do
  • How many rooms, windows or areas are involved
  • How easy the joints are to reach
  • Whether there’s mould to deal with

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Access, such as stairs, a lift or height
  • The rough size of the job
  • A few pictures by email, if you can
  • Whether it’s a home or a business

We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details and send pictures if you have them.

Mill End homes and their sealant

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 Rickmansworth station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like St Peter's Church of England Voluntary Aided Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
