Floor joint sealing in Hornchurch

We seal floor joints in homes, offices and commercial buildings across Hornchurch. We start by checking the floor type and the joint, since that decides which sealant suits. If you have open joints around bathroom floor edges and worn sealant at door thresholds, we can help.

London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, 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.

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.

New homes and floors in Hornchurch

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.

If you look after a church, hall or community building such as Saint George's Church, joints in its floors, skirtings and thresholds need resealing as they wear. As a London address, Hornchurch can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Leave it or put it right?

The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Hornchurch, the repair is bigger than the sealant job would have been.

Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What we’re called out for in Hornchurch

Water and dirt collect in open floor joints. In kitchens and bathrooms, mop water gets into the gap and behind skirting and plinths.

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

  • Gaps opening between the floor and skirting
  • Floor edges that trap water and grime
  • Open joints around bathroom floor edges
  • Perimeter joints in tiled floors filled with grout

If you let a flat or house near Emerson Park station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

  • The length of the guarantee
  • How the colour is chosen
  • How the joint is cleaned and prepared

10 questions to ask before you book

Hornchurch questions

Is Hornchurch in your area for floor joint sealing?

Yes, Hornchurch is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Do you offer different sealant colours?

In most cases you can choose. We’ll explain which colours are available.

Do you hold any approvals?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Do you work on commercial floors?

Yes, including warehouses, units, shops and offices. Work can be planned around your hours, and out-of-hours work can be arranged.

How long before the joint can take traffic?

We’ll tell you before we leave. That depends on the product, and walking on it generally comes before mopping or wheeled traffic.

Can new sealant go over the old?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Which products do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.

What happens on the day

Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours, depending on the length of joint, depending on the size of the job. In Hornchurch, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  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. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

Advice

Honest limits

In fairness, some problems need a different trade:

  • Subfloor problems that need a flooring contractor
  • A tiled floor that needs relaying
  • Water getting under the tiles from elsewhere

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

Where we work in Hornchurch

  • Commercial floors
  • Concrete floor joints
  • Thresholds
  • Tiled floors
  • Skirting boards
  • Wet room & bathroom floors

Surface by surface

Wet room and bathroom floors

Wet room floors rely on sound joints at the walls. It’s resealed with a sanitary silicone and we will say if the problem looks like more than the joint.

Tiled floors

The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Check skirting joints after the heating season
  • Lift furniture rather than dragging it across joints
  • Avoid caulk in bathrooms and kitchens
  • Keep floor cleaning water to a minimum at the edges

Follow the cure time before walking on or cleaning the joint. Feet are generally fine before mopping or wheeled traffic so we will give you each time.

In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
