Northington Floor Joint Sealing
Floor joint sealing across Northington and nearby, with every bit of old sealant taken out first.

- Floor edges that trap water and grime
- Skirting caulk that keeps splitting
Floor joint sealing in Northington
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We work on wet room & bathroom floors, skirting boards and thresholds, and the jobs we see most are gaps at thresholds between rooms and failed seals where bathroom floors meet baths and panels.
For a small place like Northington, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
We stand behind the work with a 12-month guarantee.

What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes a few hours, depending on the length of joint. For a village or hamlet like Northington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- 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.
How to prepare
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

How the job changes by surface
Tiled floors
Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant in a matching colour.
Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.
New homes and floors in Northington
Across Hampshire, 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. That’s why the skirting and threshold joints need a flexible seal.
Community buildings like Church of St John the Evangelist are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Don’t slide heavy items over sealed joints
- Cone off fresh joints until they’re ready
- Check skirting joints after the heating season
- Keep caulk for dry, still joints only
Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact.
Your questions about floor joint sealing in Northington
Can you do floor joint sealing in Northington?
Yes, Northington is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Is Northington within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you have insurance?
Yes, we’re fully insured.
Will I be able to paint over the new joint?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone won’t take paint, so it’s kept for wet areas and unpainted joints.
Can you use decorators’ caulk instead?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.

What else we do in Northington
Why deal with it now?
Filling a skirting gap with caulk looks fine at first, so the gap reappears. A flexible sealant stretches instead. In a small place like Northington, 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.
