What affects the cost of remedial sealant

- The number of rooms or windows
- The number and length of the joints
- Whether there’s mould to deal with
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Remedial sealant in Poyle
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We work on mouldy bath & shower sealant, expansion joints and botched or over-sealed joints, and the jobs we see most are gaps opening along the back of the worktop and decorators’ caulk around a bath or shower.
For a small place like Poyle, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any 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.

How it works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on how many layers have to come out in most cases. In a small place like Poyle, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

Surface by surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
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 with a low-modulus product.
Keeping the joints in good condition
Aftercare is simple:
- Do not add new sealant on top of old
- Act on a lifting corner straight away
- Never fill a movement joint with mortar or grout
- Check trays and worktops don’t move
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Your questions about remedial sealant in Poyle
Can you help a landlord with a rental near Heathrow Terminal 5 Rail station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Poyle?
Yes, Poyle is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What if the leak isn’t the sealant?
In that case, we tell you what we have found. A plumber or fitter may be needed before any new sealant goes on.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Poyle homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings. There are hotels and other places to stay in and around Poyle. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Letting a property close to Heathrow Terminal 5 Rail station? Then a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Church of St Thomas, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Managing a site like Pippins 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.
Poyle is about 3 miles north of Staines-upon-Thames, in Slough. Poyle gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Poyle is one of 31 places in Slough we cover. We also work in London, around 18 miles away.
Our applicators cover all of the SL3 postcode area for remedial sealant. If you need remedial sealant at a property on Poplar Close, Sherborne Close and Bath Road or a nearby road, our applicators can take on the job. We also cover the places around Poyle: Colnbrook (1 mile north-west), Horton (1 mile south-west), Brands Hill (1 mile west), Stanwell Moor (1 mile south-east) and Sunnymeads (2 miles west). Within a short drive, we also cover Slough (5 miles north-west), Cippenham (6 miles north-west), Chalvey (5 miles north-west), Britwell (6 miles north-west), Langley (3 miles north-west) and Upton (4 miles north-west).
Around Poyle
We work in homes and buildings around Langley Grammar School, Arthur Jacob Nature Reserve and The Punch Bowl pub, among other places. Poyle’s nearest station is Heathrow Terminal 5 Rail station, about 1.2 miles south-east. A little further out are Spelthorne Museum (3.2 miles south) and Windsor Castle (3.9 miles west). Open spaces near Poyle include Crane Meadows and Staines Reservoirs.
Leave it or put it right?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like Poyle, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Movement from fittings that are not supported
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.
