Floor joint sealing in Addiscombe

Different surfaces, different methods

Skirting boards

On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is generally better.

Thresholds

Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.

How we handle floor joint sealing in Addiscombe

We seal floor joints in homes, offices and commercial buildings across Addiscombe. We start by checking the floor type and the joint, since that decides which sealant suits. Typical jobs include dirt and water collecting in open floor joints and grout used at the floor edge instead of sealant, across wet room & bathroom floors, skirting boards and thresholds.

Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Why it’s worth doing now in Addiscombe

Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant stretches instead. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Related advice

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Quotes for floor joint sealing in Addiscombe

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

  • Mould in or behind the old joints
  • When we can work, for business premises
  • The product the joint needs
  • How many rooms, windows or areas are involved

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Helping us quote

To make quoting easier, please include:

  • What the problem is, such as mould, gaps, leaks or cracking
  • A few photos by email, if you can
  • Whether it has been sealed before
  • Whether it’s a home or a business

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

Floor joint sealing around Addiscombe

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
