New build mastic in Lea Bridge

New homes and floors in Lea Bridge

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.

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

About our new build mastic in Lea Bridge

For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you are dealing with joints pulling apart as timber shrinks and leaking shower tray seals in a new home, we can help.

Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.

You get a one-year guarantee, the same in Lea Bridge as everywhere else we work.

What affects the cost of new build mastic

We do not publish a price list. What we look at:

  • The type of sealant required
  • How many areas need sealing
  • Any mould that needs treating
  • The amount of work

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What we need to know

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The address or postcode of the job
  • Pictures of the joints, sent by email
  • The rough size of the job
  • Any access issues, like height or stairs

We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job.

Landlords, agents and businesses in Lea Bridge

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. For a job in Lea Bridge, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. The old bead comes out in full, with no layer left behind.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. Finally, each room is checked and you’re given the cure time.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Tell us if parking is tricky
  • Clear the area around the work

Lea Bridge questions

Is Lea Bridge in your area for new build mastic?

Yes, Lea Bridge is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Can parking be tricky for a visit in Lea Bridge?

Parking in Lea Bridge, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How long will you be here?

As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer.

Are you ARBOMaster approved?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

How long before the joint can be used?

Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.

Do you work for developers?

Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.

Do you need new build mastic in Lea Bridge?

The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracked sealant shows up.

The problems people generally mention when they call are:

  • Gaps opening as the house dries out and settles
  • Skirting joints opening in the first winter
  • Second-fix sealing on new plots
  • Sealant applied over dusty or wet surfaces

Lea Bridge is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Choosing a sealant specialist

When something else is needed

A few problems are outside what sealant work can do:

  • Your warranty claim itself, which is between you and the builder
  • Damaged fittings that need replacing
  • A tray or bath that isn’t properly supported, until it’s fixed

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Where we work in Lea Bridge

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

DIY sealant or a professional job?

If you’re set on DIY, put the effort into 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.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Why act early in Lea Bridge

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 drop us an email with a few photos and we’ll give you a straight answer. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

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.
