Floor joint sealing in Upper Street
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant so water and dirt cannot get in. We work on skirting boards, thresholds and wet room & bathroom floors, and people most often call us about grout cracking in a straight line across a floor and rigid edge joints in tiled floors.
For a small place like Upper Street, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Aftercare tips
Looking after new joints is easy:
- Check the sealant is paintable before decorating
- Sweep along the edges of the floor
- Avoid sloshing water against skirting
- Look at floor joints each spring
Don’t paint over silicone. If you plan to paint, we’ll use a paintable product.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier.
New homes and floors in Upper Street
Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
For buildings such as Church of St Mary, floor and skirting joints in halls and kitchens wear like any others.

What happens if it’s left?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant moves with the floor and keeps the joint sealed. In a small place like Upper Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for most rooms, longer for large commercial floors. Somewhere as small as Upper Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and tooled.
- We check the joints and explain the aftercare.
Preparing for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Advice
Signs you need floor joint sealing in Upper Street
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.
Keep an eye out for any of the following:
- Rigid edge joints in tiled floors
- Chipped and open joints in warehouse floors
- Gaps opening between the floor and skirting
- Failed seals where bathroom floors meet baths and panels
For site and facilities teams at buildings such as Breamore Church of England Primary School, entrance and corridor floor joints take a lot of traffic.

FAQs for Upper Street
Is Upper Street in your area for floor joint sealing?
Yes. We work across London and the South East, and Upper Street is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
Is there a guarantee on floor joint sealing in Upper Street?

Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Do you work on commercial floors?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor and we’ll quote.
How long does floor joint sealing take?
Most jobs take a morning or an afternoon for most homes, including preparation and clearing up. We’ll confirm how long when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Why does the gap under my skirting keep coming back?
Timber floors and skirting shrink and swell through the year. We close it with a flexible sealant that moves with the floor.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
