Joints and finishes in Gosmore homes
Across Hertfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.
Managing a site like St Ippolyts Church of England Aided Primary School? Then entrance and corridor floor joints take a lot of traffic. For landlords with property near Hitchin station, gaps at skirtings and thresholds are worth sealing between tenancies.

Floor joint sealing in Gosmore
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We work on thresholds, tiled floors and concrete floor joints, and the jobs we see most are perimeter joints in tiled floors filled with grout and dirt and water collecting in open floor joints.
Around Gosmore, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What affects the cost of floor joint sealing
Call for a quick quote. What matters most is:
- The amount of work
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Helping us quote
When you call or email, it’s useful to know:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- How we’d reach the joints
- The rough size of the job
We quote each job on its own, so start by telling us what you need. Just ring 0345 464 0079 or email us with the details and send photos if you have them.
What we’re called out for in Gosmore
Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits.
Signs it’s time to call us include:
- Open joints that fill with dirt
- Chipped and open joints in warehouse floors
- Threshold joints that have opened or worn
- Tiled floors with no room to move
Community buildings like Church of St Ippolyts (church of England) are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Why deal with it now?
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. In a small place like Gosmore, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why choose Mr Mastic in Gosmore
- Sealant colour chosen to suit
- White, clear, grey or coloured to suit, where the product allows
- Approved under the ARBOMaster scheme
- Rated 4.9 stars on Google
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Lift furniture rather than dragging it across joints
- Walk round the room once a year and look at the edges
- Ask before painting over a sealed joint
- Use a well-wrung mop rather than flooding the floor
Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal early on.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Gosmore questions
Will you come out to Gosmore?
Yes. Gosmore is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Gosmore in your area for floor joint sealing?
Yes. Our work covers London and the South East, and Gosmore is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
When can I walk on the floor?
You will get the times before we go. It depends on the sealant, and walking on it normally comes before mopping or wheeled traffic.
Why does the gap under my skirting keep coming back?
Normally it’s movement: heating drying the timber, or a filler that is too rigid. A flexible sealant stays closed as the floor moves.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most rooms, longer for large commercial floors. In a small place like Gosmore, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and smooth it.
- We check the joints and explain the aftercare.
How to prepare

- Mention if the joints have been sealed before
- Mention any tricky access
