New build mastic for Woodway homes and businesses

New build mastic in Woodway

Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. Common call-outs are for internal frame sealant that has split and second-fix sealing on new plots, across bathrooms & en suites, skirting & floors and plot handovers.

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

Whatever the size of the job, it’s backed by our 12-month guarantee in Woodway and across Oxfordshire.

DIY sealant or a professional job?

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.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Woodway questions

Do you cover Woodway for new build mastic?

Yes. We work across London and the South East, and Woodway is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.

Can you help a landlord with a rental near Cholsey station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.

My new home is still under warranty. Should I contact you?

Start with the builder if you are in the snagging or warranty period. If it is not resolved, we will cut it out and reseal it.

Can you quote for more than one area?

Yes. Several rooms, windows or areas can go on one quote.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

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

No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.

How long should I leave it?

Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Why it’s worth doing now in Woodway

A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few photos. Around Woodway, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Why book with us

  • We never seal over old sealant
  • Tidy, careful work
  • You choose the colour before work begins
  • Fully insured

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Raise failed sealant with the developer while you are covered
  • Avoid running a DIY bead over the old one
  • Do not wait for the house to settle if water is getting through
  • Watch for new gaps as the house dries out

Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.

Early snagging is easier snagging. Small faults turn into leaks if left.

Surface by surface

Plot handovers

Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.

When to call us in Woodway

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.

The problems people generally mention when they call are:

  • Messy sealant that spoils new finishes
  • Worktop and upstand sealant coming away
  • Internal frame sealant that has split
  • Skirting joints opening in the first winter

In and around Woodway, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What to look for in a quote

  • What product goes in the joint
  • How the surfaces are prepared before sealing
  • Who does the work, and how experienced they are
  • When the joint can take water or movement

What affects the cost of new build mastic

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

  • How much there is to do
  • Mould in or behind the old joints
  • How easy the joints are to reach
  • The old material and how stubborn it is

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

What we do, step by step

On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Woodway needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  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. Each area is checked and left with its cure time.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work
  • Keep pets and children clear of the area while we work
