Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Look at the sealant regularly in the first couple of years
  • Avoid scourers and strong chemicals on sealant
  • Keep water off fresh sealant until it has cured
  • Resist patching a failed seal with a tube from the DIY shop

Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.

Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.

New build mastic in West Malling

Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. Common call-outs are for worktop and upstand sealant coming away and second-fix sealing on new plots, across kitchens, windows & doors and bathrooms & en suites.

For a new home in or near West Malling, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Do you need new build mastic in West Malling?

New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open.

The most common problems we see are:

  • Frame joints opening as the plaster dries
  • Joints pulling apart as timber shrinks
  • Untidy sealant flagged on a snagging list
  • Sealant work across a run of new homes

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

Before you book anyone

  • How long the guarantee is
  • Whether VAT is included
  • When the joint can take water or movement
  • Which sealant they’ll use, and why

10 questions to ask before booking

Different surfaces, different methods

Questions from West Malling

Can you do new build mastic in West Malling?

Yes. We work across London and the South East, and West Malling is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.

Do you cover smaller places like West Malling?

Yes. West Malling is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is it worth resealing while the house is still settling?

Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.

Do the sealants smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

What does new build mastic cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Why does sealant fail so quickly in new builds?

Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.

Can landlords and businesses book you?

Yes, often. We can quote for several properties at once.

Are you insured?

Yes. We’re fully insured for every job we do.

What affects the cost of new build mastic

The quote reflects the job in front of us. We take into account:

  • Mould in or behind the old joints
  • When we can work, for business premises
  • The product the joint needs
  • The size of the job

Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

How it works

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. A visit to West Malling is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. The finished joints are checked and the cure times given.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Mention any leaks or damp you’ve noticed
  • Let us know about stairs, lifts or work at height

Advice

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 doesn’t work out, we can still put it right.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
