Floor joint sealing near Lancing

Floor joint sealing in Lancing

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. We work on thresholds, skirting boards and concrete floor joints, and common reasons people get in touch are floor edges that trap water and grime and cracked grout where a tiled floor needs a movement joint.

Homes around Lancing range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.

There’s a 12-month guarantee on every job, large or small.

The process

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a morning or an afternoon for most homes. For a job in Lancing, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • Move anything stored near the joints
  • Mention any tricky access
  • Keep children and pets away from the work area

Floor joint sealing around Lancing

Across West Sussex, 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. The joint at the skirting or threshold has to allow for that.

For site and facilities teams at buildings such as The Globe Primary Academy, entrance and corridor floor joints take a lot of traffic. Community buildings like St. Michael & All Angels are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Lancing station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

How the job changes by surface

Wet room and bathroom floors

Floor joints in bathrooms take water every day. They’re sealed with a flexible, anti-fungal silicone that keeps water out.

Thresholds

Thresholds take daily traffic, so the sealant has to be tough as well as flexible.

Your questions about floor joint sealing in Lancing

Can you help a landlord with a rental near Lancing station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.

Do you cover smaller places like Lancing?

Yes, Lancing is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you add a movement joint to a tiled floor?

Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

Is the work guaranteed?

Yes. Every job comes with our 12-month guarantee.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Do you offer different sealant colours?

In most cases you can choose. We’ll explain which colours are available and agree one before any work starts.

Is it OK to seal over old sealant?

No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Check the sealant is paintable before decorating
  • Mark off resealed joints in warehouses
  • Lift furniture rather than dragging it across joints
  • Use a well-wrung mop rather than flooding the floor

Check the joints after the first winter. If anything has opened, it’s easy to reseal.

Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.

Leave it or put it right?

Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant stretches instead and keeps the joint sealed. In a smaller place like Lancing, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us.

Why choose Mr Mastic in Lancing

  • Experience in homes, commercial sites and hotels
  • More than 20 years in sealant work
  • Old sealant always removed completely
  • A choice of colours where the product allows

Read our cost guide and what customers say.

Should I try it myself first?

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.

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.

When it is not the sealant

In fairness, some problems need a different trade:

  • Loose, hollow or cracked tiles, which need a tiler
  • Damaged concrete that needs breaking out and repairing
  • Subfloor problems that need a flooring contractor

If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
