How we handle remedial sealant in Colney Butts

In Colney Butts, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you have worktop sealant that has shrunk and split and beads that never stuck properly, we can put it right.

Smaller places like Colney Butts still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.

All of our work is guaranteed for twelve months.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Different surfaces, different methods

Windows & doors

Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.

Worktops & kitchens

Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.

Do you need remedial sealant in Colney Butts?

Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.

The problems people generally mention when they call include:

  • Movement joints that have split or pulled away
  • Mould trapped under a layer of silicone
  • Sealant that came away because the surface wasn’t prepared
  • Repeat leaks from the same joint

For an older house near a landmark such as St Mary's Church, older homes can move a little, which is hard on rigid grout and tired sealant.

How much does remedial sealant cost in Colney Butts?

Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

How long does the work take?

Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.

Is it messy?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Can you take off two layers of silicone?

Yes. We cut out all the layers and clean off the film, before resealing with a single bead.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • A leaking trap, valve or supply pipe
  • Water damage behind tiles that needs a tiler
  • A tray or worktop that needs refixing first

Leave it or put it right?

Another bead over the top won’t fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. Around Colney Butts, 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.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

How it works

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Parking around Colney Butts is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Old beads and residue are removed down to clean surfaces.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. The joint is tooled and you are told about anything else we found.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any tricky access
  • Move anything stored near the joints
