Our applicators work in Grandpont on sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

- Rigid edge joints in tiled floors
- Skirting caulk that keeps splitting
Floor joint sealing in Grandpont, done properly
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we use a flexible sealant that moves with the floor. We work on thresholds, commercial floors and wet room & bathroom floors, and common reasons people get in touch are grout cracking in a straight line across a floor and gaps at thresholds between rooms.
Where new homes go up in smaller places like Grandpont, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Why act early in Grandpont
Dirt builds up in open joints and makes the floor look worn. A neat sealed joint is easier to clean and look tidier. In an older home around Grandpont, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.

What the job involves on each surface
Wet room and bathroom floors
Wet room floors rely on sound joints at the walls. It’s resealed with a sanitary silicone, and we’ll tell you if the leak seems to come from elsewhere.
Skirting boards
Skirting-to-floor joints are a regular job for us. We take out any cracked caulk before sealing so the bead sits on a clean surface.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning or an afternoon for most homes. A visit to Grandpont is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied.
- We check the joints and explain the aftercare.

Advice
Can I do it myself?
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.
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.
What floor joint sealing looks like in Grandpont
Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
Managing a site like St Ebbe's Church of England Aided Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Community buildings like St Matthew's are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Common problems we fix in Grandpont
An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean and behind skirting and plinths.
Any of these means the joints need attention:
- Gaps opening between the floor and skirting
- Concrete floor joints that have broken down
- Rigid edge joints in tiled floors
- Threshold joints that have opened or worn

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Get cracks along tile grout lines looked at early
- Do not fill floor joints with caulk where they move or get wet
- Vacuum floor joints regularly to stop grit building up
- Walk round the room once a year and look at the edges
Avoid flooding the floor when you clean. Less water at the edges helps the joints last.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. Resealing early keeps it out.
FAQs for Grandpont
Do you cover smaller places like Grandpont?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Oxford station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you use a paintable sealant?
It depends on the sealant, so let us know first. We use a paintable flexible sealant on joints you plan to paint.
Can you match the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
