New build mastic in Bovingdon

Why deal with it now?

Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Homes in smaller places like Bovingdon can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Why book with us

  • White, clear, grey or another colour, product permitting
  • Quality sealants from Arbo and Everbuild
  • ARBOMaster approved applicator
  • Fully insured

New build mastic for homes and businesses in Bovingdon

Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We’re often asked to deal with frame joints opening as the plaster dries and sealant work across a run of new homes, on windows & doors, kitchens and show homes.

Where new homes go up in smaller places like Bovingdon, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.

Each job carries a 12-month guarantee, large or small.

How to look after the new joints

To keep the joints looking good and working properly:

  • Avoid running a DIY bead over the old one
  • Ventilate bathrooms well, especially in the first year
  • Report sealant problems to your builder during the snagging period
  • Avoid scourers and strong chemicals on sealant

Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.

Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.

When it is not the sealant

Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:

  • Settlement cracks that need a surveyor
  • Your warranty claim itself, which is between you and the builder
  • Plumbing faults behind the sealant

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

What we seal

  • Show homes
  • Bathrooms & en suites
  • Windows & doors
  • Skirting & floors
  • Plot handovers
  • Kitchens

What happens on the day

At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a job in Bovingdon, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. Each joint is checked for movement before we start.
  2. We remove the failed sealant and clean the joints.
  3. We make sure the joints are dry and prime them if needed.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions

How we quote for new build mastic

Your quote is based on your job. We look at:

  • The size of the job
  • The product the joint needs
  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Helping us quote

There’s no need for technical detail. Just tell us:

  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • Whether it’s a home or a business
  • The rough size of the job

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

Different surfaces, different methods

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.

Kitchens

Beside the sink, the joint takes water every day. A kitchen sealant goes in there.

Common problems we fix in Bovingdon

Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.

If you can see any of these, it’s time to have the joints looked at:

  • Frame joints opening as the plaster dries
  • Gaps between new skirting and floors
  • Messy sealant that spoils new finishes
  • Sealant applied over dusty or wet surfaces

For new homes near Hemel Hempstead station, it’s worth checking the sealant early, while snags are still fresh.
