How we handle floor joint sealing in Grubb Street

The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk usually cracks where there’s movement, so we close it with a flexible sealant instead. We are often asked to deal with grout used at the floor edge instead of sealant and skirting that has pulled away from the floor, on tiled floors, thresholds and skirting boards.

Around Grubb Street, 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.

We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Surface by surface

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking painted or coloured to match.

Wet room and bathroom floors

Wet room floors rely on sound joints at the walls. We reseal it with a flexible silicone suited to wet areas.

Grubb Street: your questions answered

Is Grubb Street within the area you cover?

Yes. Grubb Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Grubb Street in your area for floor joint sealing?

Yes. We work across London and the South East, and Grubb Street is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.

Why not just use caulk?

Only on dry joints that don’t move. Caulk cracks as the floor moves, so the gap comes back. A flexible sealant is the better choice.

When can I walk on the floor?

We give you a cure time for each joint. Feet are usually fine first, then mopping, then heavy wheels.

Can grout be replaced with sealant on 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.

How do I get a quote for floor joint sealing in Grubb Street?

It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.

Why does the gap under my skirting keep coming back?

Timber floors and skirting shrink and swell through the year. We close it with a flexible sealant that moves with the floor.

Can you match the sealant colour?

Generally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Vacuum floor joints regularly to stop grit building up
  • Use furniture pads near skirting
  • Check the sealant is paintable before decorating
  • Keep heavy wheels off new concrete joints until cured

Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed while it cures.

Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further and are harder to clean out.

What happens on the day

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for most rooms, longer for large commercial floors, depending on the amount of work. Somewhere as small as Grubb Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. We take out any old caulk, sealant or grout along the line.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • Move anything stored near the joints

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

For site and facilities teams at buildings such as Greenlands Primary School, entrance and corridor floor joints take a lot of traffic. Community buildings like Church of Saint Mary Magdalene are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Do you need floor joint sealing in Grubb Street?

When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, where a flexible joint should have been.

If you can see any of these, it’s time to have the joints looked at:

  • Perimeter joints in tiled floors filled with grout
  • Open gaps along the bottom of skirting boards
  • Open joints around bathroom floor edges
  • Cracked caulk along skirting in bathrooms and kitchens

Rented homes near Longfield station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

How to choose a mastic man

Leave it or put it right?

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a small place like Grubb Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why us?

  • A choice of colours where the product allows
  • A 12-month guarantee on all work
  • ARBOMaster approved applicator
  • Any old sealant cut out fully, not covered over

What sealant work cannot fix

To be straight with you, some problems need a different trade:

  • Floors that are uneven or need levelling
  • A tiled floor that needs relaying
  • Concrete repairs beyond the joint
