FAQs for Burgess Hill
Do you work for landlords with property near Burgess Hill station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Burgess Hill in your area for new build mastic?
Yes. Our work covers London and the South East, and Burgess Hill is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
How much does new build mastic cost in Burgess Hill?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
When is the best time to reseal in a new build?
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.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Burgess Hill.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
What affects the quote in Burgess Hill
Your quote is based on your job. We take into account:
- Whether the work is at height
- When we can work, for business premises
- Mould in or behind the old joints
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Roughly how big the job is
- If someone has resealed it before

When something else is needed
Before booking, it’s worth knowing the limits too:

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Ventilate bathrooms well, especially in the first year
- Keep water off fresh sealant until it has cured
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In Burgess Hill, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before we start.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours in a single home. In Burgess Hill, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely 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.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

DIY versus a professional finish
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Do you need new build mastic in Burgess Hill?
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
These are the problems we are asked about most:
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
If you’ve bought a new home near Burgess Hill station, the sealant around baths, showers and frames is worth checking in the first year or two.
