What affects the quote in Brunswick Park

We do not publish a price list, because no two jobs are the same. What we look at:

  • The number and length of the joints
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • The number of rooms or windows

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

What to tell us for a quote

To make quoting easier, let us know:

  • Whether it has been sealed before
  • How many joints, rooms or windows are involved
  • The type of property
  • How we’d reach the joints

Floor joint sealing in Brunswick Park, done properly

Painted skirting can be sealed with a flexible product that can be painted over. In wet areas we’d normally use silicone. We work on tiled floors, skirting boards and thresholds, and people most often call us about gaps at thresholds between rooms and skirting that has pulled away from the floor.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Brunswick Park and beyond.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Can you seal over the old sealant?

How much does floor joint sealing cost in Brunswick Park?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

How long will you be here?

Typically it takes a morning or an afternoon for most homes. Bigger jobs take longer, and we will say how long yours will take.

Is it messy?

We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.

Will I be able to paint over the new joint?

It depends on the sealant, so let us know first. Joints that will be painted get a paintable product and wet areas get silicone.

What floor joint sealing looks like in Brunswick Park

Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.

Brunswick Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near New Southgate station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a morning or an afternoon for most homes. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Brunswick Park. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Before we arrive

  • Mention any tricky access
  • Try not to wet indoor joints just before the visit
  • Mention any leaks or damp you’ve noticed

When something else is needed

To be straight with you, some problems need a different trade:

  • A tiled floor that needs relaying
  • Structural movement or subsidence
  • Subfloor problems that need a flooring contractor

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

Where we work in Brunswick Park

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

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

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

Silicone sealant is not made to take paint. If you plan to paint, we’ll use a paintable product.

In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Different surfaces, different methods

Thresholds

Threshold joints get a lot of feet, so the sealant has to be tough as well as flexible.

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.

Signs you need floor joint sealing in Brunswick Park

Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands and joints fail.

Most people get in touch after spotting something like this:

  • Skirting that has pulled away from the floor
  • Worn sealant at door thresholds
  • Grout cracking in a straight line across a floor
  • Grout used at the floor edge instead of sealant

Schools such as St Andrew the Apostle Greek Orthodox School are buildings too, and entrance and corridor floor joints take a lot of traffic.
