New homes and floors in Beddington

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

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

New build mastic for homes and businesses in Beddington

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 plot handovers, show homes and bathrooms & en suites, and people most often call us about gaps behind new kitchen upstands and sealant applied over dusty or wet surfaces.

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.

Your job is guaranteed for a year, as with all our work.

Honest limits

We’ll always be straight with you, so here’s what new sealant will not do:

  • Leaking fittings rather than failed sealant
  • Cracked trays, tiles or worktops
  • Structural cracks in walls or ceilings

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

Joints and surfaces we work on

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

What happens if it’s left?

A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Beddington.

The cost depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Why book with us

  • Any old sealant cut out fully, not covered over
  • An ARBOMaster approved applicator
  • Every job guaranteed for a year
  • More than 20 years in sealant work

Work for landlords, hotels and businesses

If you manage several properties in or around Beddington, several properties can go on one quote. Send us the addresses and the work at each.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.

How to look after the new joints

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

  • Clean sealant with mild detergent, not abrasives
  • Keep water off fresh sealant until it has cured
  • Don’t seal over failed sealant yourself
  • Report sealant problems to your builder during the snagging period

Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.

What affects the quote in Beddington

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

  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • Whether the work is at height
  • The product the joint needs

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

Asking for a quote

To make quoting easier, let us know:

  • The address or postcode of the job
  • If someone has resealed it before
  • If it’s domestic, commercial or a hotel
  • Pictures of the joints, sent by email

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.

The process

Once we are on site, 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 a few hours in a single home. In Beddington, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely, with no layer left behind.
  3. We clean out the dust and grit left from the build.
  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.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Clear items away from the joints we are working on
  • Mention any leaks or damp you’ve noticed

How to get a quote

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

FAQs for Beddington

Can parking be tricky for a visit in Beddington?

Parking in Beddington, 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 you do new build mastic in Beddington?

Yes. We work across London and the South East, and Beddington is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

Will you just run a new bead over the existing one?

No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

What do you need from me for a quote?

The location, the problem and the rough size of the job. Photos by email help too.

How long does new build mastic take?

That depends on how much there is to do, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will tell you when we quote.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Can you do several jobs on one visit?

Yes. Just list everything you need.

Common problems we fix in Beddington

If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.

The most common problems we see are:

  • Beads laid onto grit and dust from the build
  • Plot mastic for developers ahead of handover
  • Frame joints opening as the plaster dries
  • New-build shower sealant that has already split

As a London address, Beddington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
