About our floor joint sealing in Coldharbour

Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. If you are dealing with skirting that has pulled away from the floor and cracked grout where a tiled floor needs a movement joint, we can help, whatever the surface.

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

Your job is guaranteed for a year, as with all our work.

Quotes for floor joint sealing in Coldharbour

We quote each job individually. This is what makes a difference:

  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • The number and length of the joints
  • Working hours on commercial sites

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Helping us quote

What to tell us when you ask for a quote:

  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode
  • Any access issues, like height or stairs
  • If someone has resealed it before

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

What we do, step by step

We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a morning or an afternoon for most homes. In a small place like Coldharbour, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied.
  5. Finally, we check the work and talk you through aftercare.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before

Floor joint sealing around Coldharbour

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

For buildings such as Parish Church of St John, floor and skirting joints in halls and kitchens wear like any others. Rented homes near Hildenborough station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Damaged concrete that needs breaking out and repairing
  • Floors that are uneven or need levelling
  • A tiled floor that needs relaying

If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Surfaces we seal

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

Looking after it afterwards

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

  • Lift furniture rather than dragging it across joints
  • Check the sealant is paintable before decorating
  • Keep floor cleaning water to a minimum at the edges
  • Get cracks along tile grout lines looked at early

Keep off the joint for the time we give you. Feet are usually fine before mopping or wheeled traffic, and we’ll tell you both.

Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.

FAQs for Coldharbour

Will you come out to Coldharbour?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is Coldharbour in your area for floor joint sealing?

Yes, Coldharbour is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can I choose the sealant colour?

In most cases you can choose. We will explain which colours are available.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

How long before the joint can take traffic?

We give you a cure time for each joint. Feet are generally fine first, then mopping, then heavy wheels in most cases.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.

Why deal with it now?

Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. Around Coldharbour, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

When to call us in Coldharbour

New floors settle once they’re in use. Gaps at the edges appear in the first year or so and anything rigid cracks.

Any of these means the joints need attention:

  • Floor edges that trap water and grime
  • Gaps opening between the floor and skirting
  • Grout cracking in a straight line across a floor
  • Cracked caulk along skirting in bathrooms and kitchens

If you look after a building such as St Margaret Clitherow Catholic Primary School, entrance and corridor floor joints take a lot of traffic.

Questions to ask before you book

  • What guarantee comes with the work
  • How much experience the applicator has
  • Whether they’re fully insured
  • What happens if they find a problem under the old sealant

How to choose a mastic man

Different surfaces, different methods

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

Wet room and bathroom floors

Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone that keeps water out.
