How we handle floor joint sealing in Waltham St Lawrence
Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is usually the better choice. Common call-outs are for threshold joints that have opened or worn and floor edges that trap water and grime, on skirting boards, wet room & bathroom floors and thresholds.
Around Waltham St Lawrence, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning or an afternoon for most homes, and the area is left clean. Somewhere as small as Waltham St Lawrence, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
Getting a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.

Aftercare tips
Looking after new joints is easy:
- Have a cracking tiled floor checked before tiles break
- Keep caulk for dry, still joints only
- Vacuum floor joints regularly to stop grit building up
- Use furniture pads near skirting
Follow the cure time before walking on or cleaning the joint. Feet are generally fine before mopping or wheeled traffic, and we will tell you both.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Surface by surface
Wet room and bathroom floors
Bathroom floor edges get wet at every clean. A flexible seal stops water running into the gap.
Tiled floors
Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines in a matching colour.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Water getting under the tiles from elsewhere
- Concrete repairs beyond the joint
- Movement too big for a sealant joint
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on

What happens if it’s left?
Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now for most homes. Older cottages and farmhouses around Waltham St Lawrence can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits. We’ll give you a clear price for the lot.

New homes and floors in Waltham St Lawrence
Across Wokingham, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same 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 Lawrence, floor and skirting joints in halls and kitchens wear like any others. Managing a site like Waltham St Lawrence Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. For landlords with property near Twyford station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
