About our new build mastic in Shirkoak
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. If you have worktop and upstand sealant coming away and smeared, uneven beads picked up at snagging, we can put it right, on bathrooms & en suites, skirting & floors and windows & doors alike.
Older homes in small places like Shirkoak often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work is covered by our 12-month guarantee.

Aftercare tips
Looking after new joints is easy:
- Put sealant faults on your snagging list early
- Record problems with dated photos
- Keep water off fresh sealant until it has cured
- Watch for new gaps as the house dries out
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.

How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- Any working-time requirements on site
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that is easy
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
When to call us in Shirkoak
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Any of these means the joints need attention:
- Gaps between new skirting and floors
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
For new homes near Ham Street station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Which colour the sealant will be
- When the joint can take water or movement
- The length of the guarantee
- How hidden problems are handled
What else we do in Shirkoak
How the job changes by surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors to the agreed spec.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere like Shirkoak needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
