About our remedial sealant in Great Kingshill
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you are dealing with mould trapped under a layer of silicone and sealant applied over old sealant that has lifted, we can put it right.
Somewhere as small as Great Kingshill, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Whatever the size of the job, you get the same 12-month guarantee in Great Kingshill and across Buckinghamshire.

Questions from Great Kingshill
I let a flat near Great Missenden station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover Great Kingshill for remedial sealant?
Yes, Great Kingshill is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
What if resealing will not fix my leak?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, and we will not reseal for the sake of it.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you insured?
Yes, we’re fully insured.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- A bath, tray or worktop that moves until it’s properly fixed
- A tray or bath that is cracked
- Older mastics that may need an asbestos check before removal
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.

How the visit works
Most of a good job is in the preparation, so that is 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 a typical bath or shower, longer where several layers have been applied. In a small place like Great Kingshill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Advice
What affects the quote in Great Kingshill
We do not publish a price list, because jobs vary so much. What we look at:
- How many areas need sealing
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can

Different surfaces, different methods
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and point out any existing damage.
Mouldy bath & shower sealant
Repeat mould normally points to a damp, poorly aired room. We’ll reseal and tell you if extraction looks to be the issue.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Landlord and commercial work in Great Kingshill
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Leave it or put it right?
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. Where a wall is exposed, as many are in small places like Great Kingshill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Bathrooms and kitchens in Great Kingshill
Hard water is the norm across most of the South East, so limescale builds up 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 Great Missenden station, botched sealant from a previous quick fix is easier to strip out between tenants. Homes close to Church of the Good Shepherd include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Great Kingshill Church of England Combined School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
