Why act early in Newnham Murren

DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Around Newnham Murren, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Remedial sealant for homes and businesses in Newnham Murren

Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. If you’re dealing with wide, uneven beads that look worse than the old ones and black mould underneath the bead, we can help, whatever the surface.

In a village or hamlet like Newnham Murren, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

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.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Landlords, agents and businesses in Newnham Murren

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Never fill a movement joint with mortar or grout
  • Do not wait for a small gap to become a leak
  • Look for stains below bathrooms now and then
  • Report a tray that rocks or a worktop that lifts

Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.

A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.

Newnham Murren 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.

In the older streets around Church of St Mary Magdalene, older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Crowmarsh Gifford Church of England School? Then 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.

10 questions to ask before booking

Newnham Murren questions

Is Newnham Murren in your area for remedial sealant?

Yes. We work across London and the South East, and Newnham Murren is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.

I let a flat near Cholsey station. Can you help?

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

Do you fix expansion and movement joints?

Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.

Do you remove the old sealant?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

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

It takes a few hours, depending on how many layers have to come out. We’ll give you a timescale when we quote.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

The process

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Newnham Murren, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we find out how and where the joint has failed.
  2. All the old sealant comes out, including any layers underneath.
  3. We clean the joint, treat any mould and let it 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.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about earlier repairs to the joints

Advice

What the job involves on each surface

Leaking trays & enclosures

A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.

Mouldy bath & shower sealant

Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
