Floor joint sealing for homes and businesses in Great Amwell
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant in a matching colour. If you’re dealing with floor edges that trap water and grime and rigid edge joints in tiled floors, we can help, whatever the surface.
For a small place like Great Amwell, the journey and access are planned in advance, and the work itself is the same as on any site.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Questions from Great Amwell
Do you work for landlords with property near St Margarets (Herts) station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you do floor joint sealing in Great Amwell?
Yes, Great Amwell is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
What causes gaps between the floor and skirting?
Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
My floor grout keeps cracking in a line. Can you help?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant, giving the floor room to move.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Common problems we fix in Great Amwell
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting and anything rigid cracks.
Look out for these signs:
- Chipped and open joints in warehouse floors
- Skirting caulk that keeps splitting
- Tiled floors with no room to move
- Floor edges that trap water and grime
For buildings such as Parish Church of St John the Baptist, joints in its floors, skirtings and thresholds need resealing as they wear.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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, and the work is guaranteed for a year.
