Floor joint sealing for Norwood New Town homes and businesses

Surface by surface

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint if it’s in the right place.

Commercial floors

In commercial buildings, we can plan floor joint work around opening hours. Out-of-hours working can be arranged where it’s needed.

Floor joint sealing in Norwood New Town, done properly

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We’re often asked to deal with gaps at thresholds between rooms and gaps opening between the floor and skirting, on commercial floors, tiled floors and concrete floor joints.

New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

Big or small, you get the same 12-month guarantee in Norwood New Town and across Greater London.

Leave it or put it right?

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Norwood New Town.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Look at floor joints each spring
  • Lift furniture rather than dragging it across joints
  • Check the sealant is paintable before decorating
  • Sweep along the edges of the floor

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed while it cures.

Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.

How it works

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours, depending on the length of joint from start to finish. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  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. Finally we tool it smooth and explain when the floor can be used and cleaned.

What floor joint sealing looks like in Norwood New Town

Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.

As a London address, Norwood New Town can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a building such as Rockmount Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. If you look after a church, hall or community building such as New Covenant Church-Equipping People, joints in its floors, skirtings and thresholds need resealing as they wear.

Questions from Norwood New Town

Do you cover Norwood New Town for floor joint sealing?

Yes. Our work covers London and the South East, and Norwood New Town is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Do you work for landlords with property near Gipsy Hill station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

Do you have insurance?

Yes. We’re fully insured for domestic and commercial work.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you take out the old sealant first?

Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

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.
