Floor joint sealing in Northway
Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. If you are dealing with grout cracking in a straight line across a floor and grout used at the floor edge instead of sealant, we can put it right, on skirting boards, wet room & bathroom floors and thresholds alike.
For a new home in or near Northway, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You get a one-year guarantee, the same in Northway as everywhere else we work.

Why act early in Northway
An open concrete floor joint gets wider every time something heavy crosses it. Resealing it early protects the edges. Around Northway, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost 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, so you know where you stand.

Common problems we fix in Northway
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting.
Any of these means the joints need attention:
- Gaps at thresholds between rooms
- Failed seals where bathroom floors meet baths and panels
- Cracked grout where a tiled floor needs a movement joint
- Skirting that has pulled away from the floor
Community buildings like St Anthony of Padua are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- The joint is tooled neatly and the cure time explained.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Move anything stored near the joints

How the job changes by surface
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges and keeps dirt out.
