Our new build mastic service in Slough
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. We work on bathrooms & en suites, plot handovers and kitchens, and people most often call us about worktop and upstand sealant coming away and sealant applied over dusty or wet surfaces.
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

New homes and floors across Slough
Homes across Slough range from older properties with timber floors to new builds settling in. Skirting, threshold and floor joints open up in both, as floors move and new buildings settle.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. Whatever the job in Slough, surfaces are cleaned back properly before new sealant goes in.
Slough: In and around Slough, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Slough station, the sealant around baths, showers and frames is worth checking in the first year or two.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. If you are unsure which you have, ring 0345 464 0079 or email us with photos and we’ll tell you.

Quotes for new build mastic in Slough
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- When we can work, for business premises
- How many rooms, windows or areas are involved
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- The address or postcode of the job
- How many joints, rooms or windows are involved
Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job, and photos are welcome.
For landlords and businesses
Landlords and letting agents in Slough can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
- Put sealant faults on your snagging list early
- Ventilate bathrooms well, especially in the first year
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Slough: your questions answered
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
Do you cover Slough?
We do. Our applicators work in Slough, and the service is the same as everywhere else.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
