About our new build mastic in Lower Bourne
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Common call-outs are for messy sealant that spoils new finishes and gaps between new skirting and floors, across show homes, bathrooms & en suites and windows & doors.
In smaller places like Lower Bourne, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common problems we fix in Lower Bourne
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Signs it’s time to call us include:
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
If you’ve bought a new home near Farnham station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book

- How the colour is chosen
- The length of the guarantee
- What insurance they hold
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Around Lower Bourne, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

When something else is needed
Before booking, it’s worth knowing the limits too:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing

If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Show homes
- Windows & doors
- Bathrooms & en suites
- Plot handovers
- Kitchens
- Skirting & floors
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Raise failed sealant with the developer while you’re covered
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Use the extractor fan every time you shower
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- The type of sealant required
- Working hours on commercial sites
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- Whether it’s a home or a business
- Photos by email, if that’s easy
- If someone has resealed it before
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or drop us an email with the details.

The process

If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.

Is there any odour?

Why has my new-build shower seal failed already?
