Common problems we fix in High Cross

Water and dirt collect in open floor joints. In kitchens and bathrooms, mop water gets into the gap and can reach the subfloor.

Any of these means the joints need attention:

  • Concrete floor joints that have broken down
  • Grout used at the floor edge instead of sealant
  • Cracked caulk along skirting in bathrooms and kitchens
  • Open joints around bathroom floor edges

If you look after a church, hall or community building such as The Parish Church of St Denys, floor and skirting joints in halls and kitchens wear like any others.

Before you book anyone

  • Which colour the sealant will be
  • How the surfaces are prepared before sealing
  • What product goes in the joint

How to choose a mastic man

Floor joint sealing in High Cross

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt cannot get in. If you’re dealing with gaps between floors and kitchen plinths and concrete floor joints that have broken down, we can help, whatever the surface.

For a small place like High Cross, the journey and access are planned in advance, and the work itself is the same as on any site.

Whatever the size of the job, you get the same 12-month guarantee.

New homes and floors in High Cross

Across East Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

Rented homes near Crowborough station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as Rotherfield Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Leave it or put it right?

Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant moves with the floor and keeps the joint sealed. In a small place like High Cross, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What you get with us

  • We agree the colour with you first
  • We leave the area clean and tidy
  • Trusted Arbo and Everbuild sealants
  • An ARBOMaster approved applicator

Common questions in High Cross

Do you cover High Cross for floor joint sealing?

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

Do you cover smaller places like High Cross?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do the sealants smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.

Can you add a movement joint to a tiled floor?

Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.

How soon can the floor be mopped?

We will tell you before we leave. It depends on the sealant, and walking on it generally comes before mopping or wheeled traffic.

Is it OK to seal over old sealant?

No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

What does floor joint sealing cost?

It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and let us know what needs doing and where.

What we do, step by step

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors, including the tidy-up. Somewhere like High Cross needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at the gap and the floor type and agree the right sealant.
  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. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Tell us about any water getting in
  • Tell us if parking is tricky

Advice

How we quote for floor joint sealing

The price is agreed before any work begins. It takes into account:

  • Whether there’s mould to deal with
  • Working hours on commercial sites
  • Access and height
  • The number and length of the joints

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

What we need to know

To make quoting easier, please include:

  • Pictures of the joints, sent by email
  • How many joints, rooms or windows are involved
  • Any previous sealing or DIY work
  • What’s wrong with the joints now

We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Check skirting joints after the heating season
  • Avoid sloshing water against skirting
  • Avoid caulk in bathrooms and kitchens
  • Get cracks along tile grout lines looked at early

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it.

Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the floor safer.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
