Floor & skirting joints in Clewer, Windsor and Maidenhead
Floor joint sealing for Clewer, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

What happens if it’s left?
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Around Clewer, 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.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

Floor joint sealing in Clewer, done properly
Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints with a sealant suited to the movement and traffic. Common call-outs are for open joints that fill with dirt and cracked grout where a tiled floor needs a movement joint, on concrete floor joints, thresholds and wet room & bathroom floors.
In smaller places like Clewer, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
Every job comes with our 12-month guarantee, wherever you are in Windsor and Maidenhead.

What affects the cost of floor joint sealing
We do not publish a price list, because jobs vary so much. The quote depends on:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The size of the job
- When we can work, for business premises
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

FAQs for Clewer
Will you come out to Clewer?
Yes. Clewer is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Windsor & Eton Central station?

Are you insured?
Yes. Mr Mastic is fully insured.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you reseal concrete floor joints in an industrial unit?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor and we will quote.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours, depending on the length of joint.

DIY versus a professional finish
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Other services in Clewer
Floor joint sealing around Clewer
Floors around Windsor and Maidenhead run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.
If you look after a church, hall or community building such as Church of St Andrew, joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Windsor & Eton Central station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a building such as St Edward's Catholic First School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
