FAQs for Pirton
Is Pirton within the area you cover?
Yes. Pirton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Hitchin station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
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 you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
About our new build mastic in Pirton
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 and if that stalls, we can do it. We work on bathrooms & en suites, skirting & floors and show homes, and common reasons people get in touch are beads laid onto grit and dust from the build and second-fix sealing on new plots.
Older homes in small places like Pirton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What happens if it’s left?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Older cottages and farmhouses around Pirton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Common problems we fix in Pirton
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Keep an eye out for these signs:
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
In and around Pirton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What sealant work cannot fix
A few problems are outside what sealant work can do:

Can I do it myself?
If you are 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 fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
