Trusted new build mastic in St Ives

New build mastic for homes and businesses in St Ives

Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly. We work on plot handovers, kitchens and bathrooms & en suites, and people most often call us about internal frame sealant that has split and untidy sealant flagged on a snagging list.

In a village or hamlet like St Ives, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

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

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Avoid scourers and strong chemicals on sealant
  • Follow the cure time we give you
  • Don’t wait for the house to settle if water is getting through
  • Raise failed sealant with the developer while you’re covered

Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.

Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.

Why act early in St Ives

For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Older cottages and farmhouses around St Ives can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.

DIY sealant or a professional job?

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.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Your questions about new build mastic in St Ives

Can you do new build mastic in St Ives?

Yes, St Ives is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

What guarantee comes with new build mastic in St Ives?

All our work, in St Ives and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Can new sealant go on top of the old bead?

No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.

How long does the job take?

As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Can tenants book the work?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Is it worth resealing while the house is still settling?

It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

What new build mastic looks like in St Ives

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Whether the job is in St Ives itself or nearby, the right material for each joint matters as much as a neat finish. Around St Ives, as everywhere, new build mastic is only as good as the preparation behind it.

What the job involves on each surface

Kitchens

Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.

Show homes

In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.

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. Most jobs then take a few hours for most snagging lists, longer for a run of plots. In a small place like St Ives, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you’re given the cure time.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Tell us if parking is tricky
  • Try not to wet indoor joints just before the visit

Advice

What affects the cost of new build mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The old material and how stubborn it is
  • Which sealant suits the joint
  • Any mould that needs treating
  • The number of rooms or windows

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

To make quoting easier, please include:

  • The problem you’ve noticed
  • Photos by email, if that’s easy
  • The rough size of the job
  • Access, such as stairs, a lift or height
