Why it’s worth doing now in Newington Butts

Leaving skirting gaps until the next decorating job lets dirt and draughts in. Sealing them now is a short job. In a flat in Newington Butts, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Floor joint sealing in Newington Butts, done properly

Across Newington Butts, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, because the right sealant depends on both. If you have concrete floor joints that have broken down and skirting caulk that keeps splitting, we can put it right, on wet room & bathroom floors, tiled floors and thresholds alike.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

What floor joint sealing looks like in Newington Butts

Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

For buildings such as Metropolitan Tabernacle, floor and skirting joints in halls and kitchens wear like any others. For landlords with property near Elephant & Castle station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Newington Butts is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Your questions about floor joint sealing in Newington Butts

Do you cover Newington Butts for floor joint sealing?

Is parking a problem for a job in Newington Butts?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

What do you need from me for a quote?

The location, the problem and the rough size of the job. Photos by email help too.

Why does the gap under my skirting keep coming back?

Usually it’s movement: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible bead keeps up with the movement.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Do you seal floor joints in bathrooms and kitchens?

Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone so water can’t get into the gap.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

Should I try DIY first?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

How the visit works

  1. We look at the gap and the floor type and agree the right sealant.
  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. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Before we arrive

  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

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.

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check the sealant is paintable before decorating
  • Don’t fill floor joints with caulk where they move or get wet
  • Lift furniture rather than dragging it across joints
  • Use a well-wrung mop rather than flooding the floor

Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant before it has fully cured.

Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen over time.
