About our new build mastic in Shillingford
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you have sealant applied over dusty or wet surfaces and kitchen sealant that has pulled off the wall, we can put it right.
Around Shillingford, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months.

Work for landlords, hotels and businesses
For anyone letting property in or around Shillingford, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Should I try it myself first?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. In a small place like Shillingford, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Around Shillingford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Common questions in Shillingford
Is Shillingford in your area for new build mastic?
Yes. We work across London and the South East, and Shillingford is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
I let a flat near Cholsey station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you have insurance?
Yes, we are fully insured.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Avoid scourers and strong chemicals on sealant
- Do not wait for the house to settle if water is getting through
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
