Different surfaces, different methods

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.

Windows and doors

On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.

New build mastic for homes and businesses in Hannington

We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with kitchen sealant that has pulled off the wall and plot mastic for developers ahead of handover, we can put it right, whatever the surface.

Work in a small place like Hannington just needs the journey and access planning, and the work itself is the same as on any site.

All of our work is guaranteed for twelve months.

When it isn’t the sealant

To be straight with you, some problems need a different trade:

  • Movement caused by a poorly fitted tray or bath
  • Cracking that points to a structural problem
  • Plumbing faults behind the sealant

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

What happens on the day

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. In a small place like Hannington, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out, with no layer left behind.
  3. Joints are vacuumed and cleaned of building dust.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

Getting ready for the visit

Why deal with it now?

If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Hannington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Why Hannington customers choose us

  • Any old sealant cut out fully, not covered over
  • 20+ years of sealant experience
  • Approved under the ARBOMaster scheme
  • A choice of colours where the product allows

Hannington questions

Is Hannington in your area for new build mastic?

Yes. We work across London and the South East, and Hannington is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Will you come out to Hannington?

Yes. Hannington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How long should I leave it?

Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.

Can landlords and businesses book you?

Yes, often. We can quote for several properties at once.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Are you fully insured?

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

Is it normal for sealant to crack in a new home?

A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.

How we quote for new build mastic

Jobs vary more than people expect. What affects the quote:

  • How many rooms, windows or areas are involved
  • The product the joint needs
  • How much old sealant there is and how hard it is to remove
  • The size of the job

Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • Roughly how big the job is
  • Photos by email, if that is easy
  • The problem you’ve noticed
  • The address or postcode of the job

For new build mastic in Hannington, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

Common problems we fix in Hannington

The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.

People usually contact us after spotting one of these:

  • New-build shower sealant that has already split
  • Beads laid onto grit and dust from the build
  • Plot mastic for developers ahead of handover
  • Messy sealant that spoils new finishes

Around Hannington, as everywhere, new build mastic is only as good as the preparation behind it.

Questions to ask before you book

  • Whether VAT is included
  • How much experience the applicator has
  • How the joint is cleaned and prepared
  • Which sealant they’ll use, and why

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
