Questions from Aaron's Hill
Can you do new build mastic in Aaron's Hill?
Yes, Aaron's Hill is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Godalming station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
Who should fix failed sealant in a new build?
Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote with our 12-month guarantee.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Why has my new-build shower seal failed already?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
New build mastic for homes and businesses in Aaron's Hill
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you have cracked caulk along new skirting and new-build shower sealant that has already split, we can help, whatever the surface.
In and around Aaron's Hill, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.

Why act early in Aaron's Hill
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In a smaller place like Aaron's Hill, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Advice
Do you need new build mastic in Aaron's Hill?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
- Leaking shower tray seals in a new home
In and around Aaron's Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before booking anyone
- What insurance they hold
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
- Ventilate bathrooms well, especially in the first year
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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 doesn’t work out, we can still put it right.
What affects the quote in Aaron's Hill
