Common questions in Sulham
I let a flat near Pangbourne station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Will you come out to Sulham?
Yes, Sulham is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you use a paintable sealant?
Where you plan to paint, we do. Silicone in bathrooms and kitchens cannot be painted so mention it when you get a quote.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Why has a gap opened under my skirting?
Floors shrink and settle, especially in the first year or two and through the heating season. Rigid fillers split, so we use a flexible sealant.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
About our floor joint sealing in Sulham
Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. We are often asked to deal with open joints that fill with dirt and skirting that has pulled away from the floor, on concrete floor joints, thresholds and tiled floors.
Around Sulham, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Sulham
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges. Around Sulham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What floor joint sealing looks like in Sulham
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.
If you look after a church, hall or community building such as Church of St Nicholas, floor and skirting joints in halls and kitchens wear like any others. Schools such as Denefield School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Keeping the joints in good condition
So the new joints stay in good condition:
- Act on grout cracks that run in a straight line
- Ask before painting over a sealed joint
- Sweep along the edges of the floor
- Don’t fill floor joints with caulk where they move or get wet
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed until it’s ready.
Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
What we can’t put right
A few problems are outside what sealant work can do:

Advice
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Signs you need floor joint sealing in Sulham
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting.
These are the problems we’re asked about most:
- Caulk that has cracked where the floor moves
- Perimeter joints in tiled floors filled with grout
- Chipped and open joints in warehouse floors
- Grout cracking in a straight line across a floor
Rented homes near Pangbourne station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.
Questions to ask before you book
- What product goes in the joint
- How long the guarantee is
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
