New build mastic for East Dean homes and businesses

New build mastic in East Dean, done properly

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on bathrooms & en suites, plot handovers and kitchens, and common reasons people get in touch are plot mastic for developers ahead of handover and internal frame sealant that has split.

Work in a small place like East Dean just needs the journey and access planning, and once on site, the job is the same as anywhere.

Big or small, you get the same 12-month guarantee.

When it isn’t the sealant

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

  • Leaks from pipes, valves or wastes, which need a plumber
  • A tray or bath that isn’t properly supported, until it’s fixed
  • Disputes or warranty claims with your builder

If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Joints and surfaces we work on

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

What we do, step by step

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. In a small place like East Dean, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We clean off dust from the build and prime the surfaces where the product needs it.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you are given the cure time.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints

Advice

Landlords, agents and businesses in East Dean

We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

How we quote for new build mastic

Every job gets its own quote. These are the things that affect it:

  • How easy the joints are to reach
  • The old material and how stubborn it is
  • The size of the job
  • Working hours on commercial sites

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

When you contact us, it’s useful to know:

  • Whether it’s a home or a business
  • Roughly how big the job is
  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or email us.

What happens if it’s left?

Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. Not sure whether yours can wait? You can call 0345 464 0079 or send us an email with a few photos. In a small place like East Dean, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.

What you get with us

  • Sealant colour chosen to suit
  • Colour agreed with you before we start
  • We leave the area clean and tidy
  • Sanitary silicone with an anti-fungal additive in wet areas

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Look at the sealant regularly in the first couple of years
  • Put sealant faults on your snagging list early
  • Do not seal over failed sealant yourself
  • Wait for the cure time before using a resealed shower

Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.

Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

What we are called out for in East Dean

If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.

Any of these means the joints need attention:

  • Messy sealant that spoils new finishes
  • Skirting joints opening in the first winter
  • Leaking shower tray seals in a new home
  • Gaps opening as the house dries out and settles

If you’ve bought a new home near Eastbourne station, the sealant around baths, showers and frames is worth checking in the first year or two.

What your quote should include

  • Whether all the old sealant comes out first
  • How the surfaces are prepared before sealing
  • What product goes in the joint
  • How long the guarantee is

Our hiring checklist

Joints and finishes in East Dean homes

East Dean is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

East Dean: your questions answered

Will you come out to East Dean?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

I let a flat near Eastbourne station. Can you help?

Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Should I go to my builder first?

While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.

Do I have to be there?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Can you reseal over the builder’s sealant?

No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.

Are you insured?

Yes. We are fully insured, and we can confirm the details when we quote.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What do you put in the joint?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
