New build mastic in Colden Common
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Common call-outs are for plot mastic for developers ahead of handover and worktop and upstand sealant coming away, across bathrooms & en suites, kitchens and show homes.
If you’ve bought a new home in or near Colden Common, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

What the job involves on each surface
Windows and doors

Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
The process
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of plots for a typical job. A visit to Colden Common is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Why it’s worth doing now in Colden Common
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. In an older home around Colden Common, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Questions from Colden Common
Can you help a landlord with a rental near Shawford station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Can you do new build mastic in Colden Common?
Yes. We work across London and the South East, and Colden Common is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Where do you work from?
We work from Crawley. Our applicators cover Colden Common, along with the rest of our area.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
