How we handle new build mastic in Warnborough Green
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Typical jobs include cracked sealant around new window and door frames and cracks appearing as a new home settles, on skirting & floors, plot handovers and bathrooms & en suites.
Around Warnborough Green, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, you get the same 12-month guarantee in Warnborough Green and across Hampshire.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
- Resist patching a failed seal with a tube from the DIY shop
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we cannot put right
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on

Landlord and commercial work in Warnborough Green
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Should I try it myself first?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Do you need new build mastic in Warnborough Green?
Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry.
Keep an eye out for these signs:
- Joints pulling apart as timber shrinks
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
In and around Warnborough Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before booking anyone

- Whether you can choose the colour
- How much experience the applicator has
- What happens if the job turns out different
Why act early in Warnborough Green
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Warnborough Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
