New homes and floors in Washington
Floors around West Sussex run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.
Community buildings like The Parish Church of St Mary are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

About our floor joint sealing in Washington
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out and stops dirt collecting. We work on wet room & bathroom floors, commercial floors and skirting boards, and people most often call us about open gaps along the bottom of skirting boards and perimeter joints in tiled floors filled with grout.
Older homes in small places like Washington often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job.

Why act early in Washington
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. Around Washington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Different surfaces, different methods
Skirting boards
Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking painted or coloured to match.
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint if it’s in the right place.
Landlords, agents and businesses in Washington
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 that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
When to call us in Washington
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits so the gap reappears.
Look out for any of the following:
- Grout cracking in a straight line across a floor
- Gaps at thresholds between rooms
- Perimeter joints in tiled floors filled with grout
- Dirt and water collecting in open floor joints
For site and facilities teams at buildings such as St Mary's CofE Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Questions from Washington
Will you come out to Washington?
Yes, Washington is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Washington in your area for floor joint sealing?
Yes, Washington is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you seal floor joints in bathrooms and kitchens?
Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone to keep mop water out.
How long does the job take?
Typically it takes a few hours for most rooms, longer for large commercial floors. Bigger jobs take longer, and we’ll say how long yours will take.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most rooms, longer for large commercial floors. For a village or hamlet like Washington, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
