About our remedial sealant in Markyate
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for sealant that came away because the surface wasn’t prepared and movement joints that have split or pulled away, on failed movement joints, expansion joints and leaking tray & enclosure joints.
In a smaller place like Markyate, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
Big or small, you get the same 12-month guarantee in Markyate and across Hertfordshire.

Bathrooms and kitchens in Markyate
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you live in an older home near Markyate Methodist Church, walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Luton Airport Parkway station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Can I do it myself?
If you do try it yourself, take your time over the 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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What affects the cost of remedial sealant
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The number of rooms or windows
- Mould in or behind the old joints
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
When you contact us, these details help:
- The problem you’ve noticed
- If someone has resealed it before
- The type of property
- How many joints, rooms or windows are involved
Need a quote? Please phone 0345 464 0079 or email us with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Markyate and across Hertfordshire. Several sites can go on one quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or bath that is cracked
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours, depending on how many layers have to come out, including the tidy-up. For a job in Markyate, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Mention any tricky access

Do you need remedial sealant in Markyate?
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
People usually contact us after spotting something like this:
- Black mould underneath the bead
- Kitchen joints letting water behind the worktop
- Sealant peeling off a dusty or damp surface
- Over-sealed joints coming away
Managing a site like Markyate Village School and Nursery? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
What to look for in a quote
- Whether the sealant suits the joint
- Who turns up on the day
- What guarantee comes with the work

FAQs for Markyate
Is Markyate in your area for remedial sealant?
Yes, Markyate is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Luton Airport Parkway station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
What if resealing won’t fix my leak?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Do you guarantee remedial jobs?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
How long does remedial resealing take?
That depends on how many layers there are and how many joints. We’ll tell you before we start.
Leave it or put it right?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. Around Markyate, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
