New build mastic for homes and businesses in Firgo
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. Common call-outs are for frame joints opening as the plaster dries and joints pulling apart as timber shrinks, across kitchens, skirting & floors and show homes.
For a small place like Firgo, the journey and access are planned in advance, and the work itself is the same as on any site.
Every job comes with a 12-month guarantee, wherever you are in Hampshire.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
Common questions in Firgo
Do you cover Firgo for new build mastic?
Yes, Firgo is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Do you work for landlords with property near Whitchurch (Hampshire) station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.

Yes. Tell us about everything you’d like done and you will get one quote.

Common problems we fix in Firgo
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Keep an eye out for these signs:
- Sealant applied over dusty or wet surfaces
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
If you’ve bought a new home near Whitchurch (Hampshire) station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in Firgo

Can I do it myself?
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 does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
