Remedial sealant in Upper Edmonton, done properly

Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant, and common reasons people get in touch are caulk or the wrong sealant used in a wet area and gaps opening along the back of the worktop.

Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Upper Edmonton more than a cosmetic job.

There’s a 12-month guarantee on every job, whatever its size.

Why act early in Upper Edmonton

Another bead over the top won’t fix a failed joint. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Upper Edmonton, the repair is bigger than the sealant job would have been.

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Take a look at what affects the cost and customer reviews.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

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. Everything old must be removed first.

Different surfaces, different methods

Windows & doors

Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.

Leaking trays & enclosures

When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.

Quotes for remedial sealant in Upper Edmonton

Some jobs are bigger than they look, and some smaller. The main factors:

  • Access and height
  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • The number of rooms or windows

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What we need to know

Before you ask for a quote, have a think about:

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

Questions from Upper Edmonton

Can you help a landlord with a rental near Silver Street station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.

Can parking be tricky for a visit in Upper Edmonton?

Parking in Upper Edmonton, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Can you quote for more than one area?

Yes, we can. More than one area can go on one quote.

Will the old sealant be removed?

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

Is remedial work guaranteed?

Yes. Every job comes with our 12-month guarantee.

My shower still leaks after a reseal. Can you sort it?

Yes, generally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.

What happens if the problem is the tray or the plumbing?

Then we explain what we have found. You may need a plumber or bathroom fitter before any new sealant goes on.

How long before the joint can be used?

It depends on the product. We tell you how long to leave it before we go.

Remedial sealant in Upper Edmonton: local notes

London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.

Managing a site like St John and St James CofE Primary 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. For landlords with property near Silver Street station, botched sealant from a previous quick fix is easier to strip out between tenants. Upper Edmonton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

When it isn’t the sealant

New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:

  • Tiles that have come away from the wall
  • Cracks in the fitting rather than the joint
  • Plumbing leaks behind walls or under trays

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

Surfaces we seal

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

What happens on the day

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. For a job in Upper Edmonton, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. We finish neatly and point out anything that needs another trade.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property
