How we handle floor joint sealing in Selsdon
Across Selsdon, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. If you’re dealing with open joints around bathroom floor edges and skirting caulk that keeps splitting, we can put it right.
Where new homes go up in smaller places like Selsdon, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
Each job carries a 12-month guarantee.

Why deal with it now?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In an older home around Selsdon, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Questions from Selsdon
Do you cover Selsdon for floor joint sealing?
Yes. We work across London and the South East, and Selsdon is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
I let a flat near Sanderstead station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
When can I walk on the floor?
It depends on the product and the conditions. Before we leave, we tell you when it can be walked on, mopped and driven over.
Can you add a movement joint to a tiled floor?
In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.
Is caulk good enough for skirting?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so a flexible sealant suits them better.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Joints and finishes in Selsdon homes
Across Surrey, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
Community buildings like St Francis are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Sanderstead station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

How we quote for floor joint sealing
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Access and height
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- The rough size of the job
- If someone has resealed it before
- The problem you’ve noticed
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
When to call us in Selsdon
Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open and they change again in summer.
These are the problems we’re asked about most:
- Gaps between floors and kitchen plinths
- Tiled floors with no room to move
- Failed joint filler in concrete floors
- Gaps at thresholds between rooms
If you look after a building such as Selsdon Primary and Nursery School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
Before you book anyone
- Who does the work, and how experienced they are
- Whether VAT is included
- Which colour the sealant will be
- Whether all the old sealant comes out first
How the visit works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job generally takes a few hours for most rooms, longer for large commercial floors, and we explain the cure time before we leave. In a smaller place like Selsdon, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

Advice
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep dirt out of the joints
- Use furniture pads near skirting
- Do not paint over silicone
- Cone off fresh joints until they’re ready
Mop with a well-wrung mop rather than flooding the floor. 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.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
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.
