About our floor joint sealing in Wallington

Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints. Common call-outs are for open joints around bathroom floor edges and cracked caulk along skirting in bathrooms and kitchens, on thresholds, commercial floors and skirting boards.

Work in a small place like Wallington just needs the journey and access planning, and the work itself is the same as on any site.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a morning or an afternoon for most homes. In a small place like Wallington, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor.
  5. We check the joints and explain the aftercare.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children

Floor joint sealing in Wallington: local notes

Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.

If you look after a church, hall or community building such as Church of St Mary, floor and skirting joints in halls and kitchens wear like any others. Letting a property close to Ashwell & Morden station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

Wallington is about 5 miles east of Letchworth, in Hertfordshire. Jobs in Wallington get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. 381 places in Hertfordshire are on our list, large and small. We also work in Chelmsford, about 31 miles from Wallington.

Work in SG7 works the same way as everywhere else we cover. If you need floor joint sealing at a property on The Street and Kit's Lane or a nearby road, our applicators can take on the job.

How to look after the new joints

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

  • Look at floor joints each spring
  • Keep floor cleaning water to a minimum at the edges
  • Keep heavy wheels off new concrete joints until cured
  • Act on grout cracks that run in a straight line

Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.

Once concrete joint edges start to break, wheels make it worse. Early resealing helps keep the joint intact.

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Wallington questions

Do you cover Wallington for floor joint sealing?

Yes, Wallington is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.

I let a flat near Ashwell & Morden station. Can you help?

Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Is there any odour?

There can be a smell while the sealant cures. Ventilation helps.

Why not just use caulk?

Only on dry joints that don’t move. It splits once the floor shifts, so the gap comes back. A flexible sealant is the better choice.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Why has a gap opened under my skirting?

Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit.

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Different surfaces, different methods

Concrete floor joints

Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.

Skirting boards

Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first.

What affects the cost of floor joint sealing

Jobs vary more than people expect. What affects the quote:

  • Working hours on commercial sites
  • How easy the joints are to reach
  • The old material and how stubborn it is
  • The number and length of the joints

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Helping us quote

When you contact us, these details help:

  • Whether it’s a home or a business
  • Whether it has been sealed before
  • The problem you’ve noticed
  • Access, such as stairs, a lift or height

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

What sealant work cannot fix

We won’t take on work that won’t last, so here’s what sealant cannot put right:

  • Cracked or broken concrete slabs
  • Large cracks that need a surveyor
  • Failed waterproofing under a wet room floor

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
