New homes and floors in Chalvey

New build mastic in Chalvey

We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Common call-outs are for beads laid onto grit and dust from the build and messy sealant that spoils new finishes, on windows & doors, bathrooms & en suites and skirting & floors.

Where new homes go up in smaller places like Chalvey, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.

There’s a 12-month guarantee on every job, large or small.

Work for landlords, hotels and businesses

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

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

What happens if it’s left?

For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In an older home around Chalvey, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Combining jobs into one visit normally makes better use of the time than several visits. We will give you a clear price for the lot.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

FAQs for Chalvey

Do you cover smaller places like Chalvey?

Yes, Chalvey is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you cover Chalvey for new build mastic?

Yes, Chalvey is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.

Is it worth trying it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Who should fix failed sealant in a new build?

Report it to the builder first while you’re covered. If it isn’t resolved, we can reseal it properly.

Do you work for landlords and businesses?

Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.

Can you match the sealant colour to my new kitchen or bathroom?

We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.

What does new build mastic cost?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.

Is there any odour?

Possibly a little. It fades as the sealant cures.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Get a leaking seal dealt with straight away
  • Raise failed sealant with the developer while you are covered
  • Avoid running a DIY bead over the old one
  • Photograph failed sealant before it’s redone

Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.

How the job changes by surface

Skirting and floors

Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.

Kitchens

Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.

How we quote for new build mastic

Jobs vary more than people expect. The main factors:

  • The product the joint needs
  • Whether there’s mould to deal with
  • The amount of work
  • How easy the joints are to reach

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What we need to know

You do not need to know the technical terms. It helps if you can tell us:

  • A few pictures by email, if you can
  • The rough size of the job
  • Where the job is, and your postcode
  • If someone has resealed it before

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.

What happens on the day

When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Parking around Chalvey is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  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. We tool every joint neatly and tell you when each area can be used.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about access, such as stairs, a lift or high-level joints
