Floor & skirting joints in St Cross, Hampshire
Problem with your floor joints in St Cross? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Gaps at thresholds between rooms
- Cracked caulk along skirting in bathrooms and kitchens
- Skirting that has pulled away from the floor
DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Floor joint sealing for homes and businesses in St Cross
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. We work on commercial floors, tiled floors and thresholds, and common reasons people get in touch are worn sealant at door thresholds and tiled floors with no room to move.
If you’ve bought a new home in or near St Cross, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Common questions in St Cross
Can you help a landlord with a rental near Winchester station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is St Cross within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you fully insured?
Yes. Full insurance covers our work.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
How long does floor joint sealing take?
Most jobs take a few hours, depending on the length of joint. Your quote will say how long we expect yours to take.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
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.
How the job changes by surface
Skirting boards
Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing so the new sealant bonds.
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.

What floor joint sealing looks like in St Cross
Across Hampshire, 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.
Schools such as St Faith's Church of England Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic. Rented homes near Winchester station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Why it’s worth doing now in St Cross
Not every floor joint takes the same sealant: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. In an older home around St Cross, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Related advice
Do you need floor joint sealing in St Cross?
Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits, which is why so many skirting joints look broken.
Look out for any of the following:
- Concrete floor joints that have broken down
- Open joints that fill with dirt
- Skirting caulk that keeps splitting
- Threshold joints that have opened or worn
For buildings such as St. Cross Church, floor and skirting joints in halls and kitchens wear like any others.
