Floor joint sealing in Southgate

Floor joint sealing in Southgate, done properly

Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone because it handles water. We work on concrete floor joints, commercial floors and tiled floors, and people most often call us about gaps opening between the floor and skirting and open joints around bathroom floor edges.

If you’ve bought a new home in or near Southgate, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.

A one-year guarantee comes as standard.

The process

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a morning or an afternoon for most homes in most cases. A visit to Southgate is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. We apply the sealant in a colour that suits the floor.
  5. The joint is tooled neatly and the cure time explained.

Getting ready for the visit

  • Mention any tricky access
  • Clear items away from the joints we are working on
  • Mention any leaks or damp you’ve noticed

Related advice

Do you need floor joint sealing in Southgate?

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges.

Keep an eye out for any of the following:

  • Failed joint filler in concrete floors
  • Gaps at thresholds between rooms
  • Gaps between floors and kitchen plinths
  • Cracked grout where a tiled floor needs a movement joint

Schools such as Southgate Primary are buildings too, and entrance and corridor floor joints take a lot of traffic.

Before booking anyone

  • Who does the work, and how experienced they are
  • Are they insured?
  • What the quote includes, VAT included or not
  • How the joint is cleaned and prepared

10 questions to ask before you book

New homes and floors in Southgate

Across West Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal. Crawley, which Southgate is part of, is one of England’s post-war new towns. Newer neighbourhoods have been added to Crawley over the years, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Newer homes need snagging; older ones need their joints renewing.

For landlords with property near Crawley station, gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as St Mary's, floor and skirting joints in halls and kitchens wear like any others.

Southgate is about 1 mile south-west of Crawley, in West Sussex. Southgate gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. We cover 371 towns and villages across West Sussex, large and small.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Southgate: your questions answered

Do you cover smaller places like Southgate?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is Southgate in your area for floor joint sealing?

Yes, Southgate is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.

Do you use a paintable sealant?

It depends on the sealant, so let us know first. We use a paintable flexible sealant on joints you plan to paint.

Do you seal kitchen plinths to the floor?

Yes. The old joint comes out and a flexible silicone replaces it.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

How soon can the floor be mopped?

We’ll tell you before we leave. That depends on the product, and light foot traffic is normally fine before wet cleaning or wheels.

Is the work guaranteed?

Yes, always. Each job is guaranteed for twelve months, wherever you are.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

When something else is needed

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • A tiled floor that needs relaying
  • Structural movement or subsidence
  • Failed waterproofing under a wet room floor

If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.

Joints and surfaces we work on

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

How we quote for floor joint sealing

The quote reflects the job in front of us. We look at:

  • How many areas need sealing
  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Photos by email, if that’s easy
  • Roughly how big the job is
  • If someone has resealed it before
  • Where the property is

For floor joint sealing in Southgate, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.

Why act early in Southgate

Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Around Southgate, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

If the skirting is painted, a paintable flexible sealant works well. In wet rooms and kitchens, silicone is normally better.
