What affects the quote in Great Wymondley

For a quick quote, just ask. What matters most is:

  • The number and length of the joints
  • Whether the work is at height
  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

What to tell us for a quote

  • The rough size of the job
  • A few pictures by email, if you can
  • The problem you’ve noticed
  • Where the property is

Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

Floor joint sealing in Great Wymondley, done properly

Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, then clean, back and seal the joint. We work on concrete floor joints, skirting boards and thresholds, and people most often call us about cracked grout where a tiled floor needs a movement joint and cracked caulk along skirting in bathrooms and kitchens.

Older homes in small places like Great Wymondley often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

Whatever the size of the job, it’s backed by our one-year guarantee.

How the job changes by surface

Concrete floor joints

Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.

Do you need floor joint sealing in Great Wymondley?

An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap.

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

  • Grout cracking in a straight line across a floor
  • Caulk that has cracked where the floor moves
  • Skirting that has pulled away from the floor
  • Chipped and open joints in warehouse floors

If you look after a building such as Wymondley Junior Mixed and Infant School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What your quote should include

  • When the joint can take water or movement
  • Who turns up on the day
  • What happens if they find a problem under the old sealant
  • How the joint is cleaned and prepared

How to choose a mastic man

Why it’s worth doing now in Great Wymondley

An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges. Where a wall is exposed, as many are in small places like Great Wymondley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

What you get with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • You choose the colour before work begins
  • Any old sealant cut out fully, not covered over
  • White, clear, grey or coloured to suit, where the product allows

What sealant work cannot fix

We will always be straight with you, so here’s what sealant cannot fix:

  • Water getting under the tiles from elsewhere
  • Large cracks that need a surveyor
  • Damaged concrete that needs breaking out and repairing

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

What we seal

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

Can I do it myself?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The process

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for most rooms, longer for large commercial floors. In a small place like Great Wymondley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. We apply the sealant in a colour that suits the floor.
  5. The joint is tooled neatly and the cure time explained.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Plan for the work area to be out of bounds to pets and children
  • Mention any sign-in or site rules at work premises

How soon can the floor be mopped?

That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over so there’s no guesswork.

How long will you be here?

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

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Is it OK to seal over old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Can you quote for more than one area?

Yes. More than one area can be quoted together.

Do you seal kitchen plinths to the floor?

Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.
