About our floor joint sealing in New Marston

We seal floor joints in homes, offices and commercial buildings across New Marston. We start by checking the floor type and the joint, since that decides which sealant suits. Common call-outs are for cracked grout where a tiled floor needs a movement joint and dirt and water collecting in open floor joints, across thresholds, tiled floors and concrete floor joints.

For a new home in or near New Marston, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the quote in New Marston

For a quick quote, just ask. The main things that affect it are:

  • How much old sealant there is and how hard it is to remove
  • The number of rooms or windows
  • Access and height
  • Working hours on commercial sites

The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

What we need to know

Before you ask for a quote, have a think about:

  • Access, such as stairs, a lift or height
  • A few pictures by email, if you can
  • What’s wrong with the joints now
  • How many joints, rooms or windows are involved

Every job is quoted individually. Just phone 0345 464 0079 or email us with the details, and photos are welcome.

How the visit works

We keep the work tidy and contained to the area we’re working on. The job normally takes a few hours for most rooms, longer for large commercial floors. Parking around New Marston is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor and smooth it.
  5. Finally, we check the work and talk you through aftercare.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can

Looking after it afterwards

So the new joints stay in good condition:

  • Don’t fill floor joints with caulk where they move or get wet
  • Avoid sloshing water against skirting
  • Check skirting joints after the heating season
  • Mark off resealed joints in warehouses

Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal before they spread.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and stops it getting worse.

Floor joint sealing around New Marston

Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

Schools such as St Michael's CofE Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. For landlords with property near Oxford station, gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a church, hall or community building such as Saint Michael and All Angels, joints in its floors, skirtings and thresholds need resealing as they wear.

Why it’s worth doing now in New Marston

Floor joints left open collect dirt that is hard to clean out, and they look untidy. A neat sealed joint is easier to clean and finishes the floor. In a smaller place like New Marston, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Different surfaces, different methods

Floor joint work in businesses can be planned around your hours. Out-of-hours working can be arranged where it’s needed.

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. Grout at the edge is removed and replaced with sealant.

New Marston questions

Will you come out to New Marston?

Yes, New Marston is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you cover New Marston for floor joint sealing?

Yes. We work across London and the South East, and New Marston is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

What causes gaps between the floor and skirting?

Usually it’s movement: heating drying the timber, or a filler that is too rigid. A flexible sealant stays closed as the floor moves.

Will it make a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

How long does floor joint sealing take?

Most jobs take a few hours, depending on the length of joint, including preparation and clearing up. Your quote will say how long we expect yours to take.

Do the sealants smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you guarantee your work?

Yes. There’s a 12-month guarantee on every job, wherever you are.
