Holland Park questions
Is parking a problem for a job in Holland Park?
Parking in Holland Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Holland Park for new build mastic?
Yes, Holland Park is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
How do I get a quote for new build mastic in Holland Park?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Should I go to my builder first?
Report it to the builder first while you’re covered. If it isn’t resolved, we’ll cut it out and reseal it.
About our new build mastic in Holland Park
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you are dealing with kitchen sealant that has pulled off the wall and beads laid onto grit and dust from the build, we can put it right.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
All our work comes with a 12-month guarantee, wherever you are in Greater London.

What we are called out for in Holland Park
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Keep an eye out for these signs:
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
If you’ve bought a new home near Kensington Olympia station, the sealant around baths, showers and frames is worth checking in the first year or two.

What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How we quote for new build mastic
Your quote is based on your job. We look at:
- Any mould that needs treating
- How many areas need sealing
- The number and length of the joints
- Whether the work is at height
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
What to tell us for a quote
What to tell us when you ask for a quote:
- How many joints, rooms or windows are involved
- The type of property
- If someone has resealed it before
- How we’d reach the joints
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.
What new build mastic looks like in Holland Park
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Holland Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What sealant work cannot fix

- A tray or bath that isn’t properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Holland Park, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Why book with us

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It usually takes a few hours for most snagging lists, longer for a run of plots. In Holland Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
