What guarantee comes with new build mastic in Great Shefford?

All our work, in Great Shefford and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Why has my new-build shower seal failed already?

A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Who should fix failed sealant in a new build?

Report it to the builder first while you’re covered. Once that is done, or if they won’t put it right, we’ll cut it out and reseal it.

Do you have insurance?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Can you work on commercial sites?

How long does new build mastic take?

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Raise failed sealant with the developer while you are covered
  • Record problems with dated photos
  • Wait for the cure time before using a resealed shower
  • Do not seal over failed sealant yourself

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.

How we quote for new build mastic

Every job gets its own quote. This is what makes a difference:

  3. Joints are dried and primed where the product calls for it.
  4. Baths are filled with water, then the new sealant is applied.
