What we are called out for in Baffins
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.
If you can see any of these, it’s time to have the joints looked at:
- Concrete floor joints that have broken down
- Grout cracking in a straight line across a floor
- Floor edges that trap water and grime
- Skirting that has pulled away from the floor
If you look after a building such as Langstone Junior Academy, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Floor joint sealing for homes and businesses in Baffins
We seal floor joints in homes, offices and commercial buildings across Baffins. We start by checking the floor type and the joint, since that decides which sealant suits. We work on tiled floors, concrete floor joints and commercial floors, and the jobs we see most are perimeter joints in tiled floors filled with grout and cracked caulk along skirting in bathrooms and kitchens.
If you’ve bought a new home in or near Baffins, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What floor joint sealing looks like in Baffins
Across Portsmouth, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
For buildings such as Church of St Cuthbert, joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Fratton station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

Why deal with it now?
The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. Homes in smaller places like Baffins can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
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. You will know the price before we begin.

Your questions about floor joint sealing in Baffins
Is Baffins in your area for floor joint sealing?
Yes, Baffins is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Do you cover smaller places like Baffins?
Yes. Baffins is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Why not just use caulk?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can sealant along the skirting be painted?
If you tell us beforehand, yes. Joints that will be painted get a paintable product and wet areas get silicone.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Different surfaces, different methods
Skirting boards
Skirting-to-floor joints are a regular job for us. The old caulk is removed first.
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.
How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on the length of joint for a typical job. For a job in Baffins, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
