Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Add sealant to the planned maintenance inspection list
- Deal with small splits before they become leaks
- Keep a record of which joints were resealed and when
- Don’t let cleaning or traffic back on before the cure time is up
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.
Sealant applicators in Aldingbourne
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on floor and threshold joints, external facade joints and movement joints in walls and floors, and the usual reasons a site gets in touch are messy, uneven beads from earlier work that let the building down and leaks that seem to come through a sealant line. Whoever orders the work in Aldingbourne, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Occupied buildings in Aldingbourne need the work phased: we agree the order with you and hand back each area with its cure time.
Rural business units near smaller places such as Aldingbourne are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Why deal with it now?
Patching the worst lengths can be the right call on a tight budget. If the rest of the bead is the same age and product, though, it’s normally close behind, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Halls, stores and units around places like Aldingbourne may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Pricing sealant joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Broken glass or blown double-glazed units
- Water from a services leak rather than a joint
- Roof leaks that only look like a joint problem
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think.

Advice
Questions we are asked in Aldingbourne
Do you cover business parks and estates near Aldingbourne, such as The Woodhorn Business Centre?
Yes. Our area takes in Aldingbourne and its surroundings, with estates and business parks such as The Woodhorn Business Centre included. Photos and a short description are enough for a first look.
Will our hotel in Aldingbourne need to close for the work?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a few hours for one area, or a planned series of visits across a bigger building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Does commercial sealant work come with a guarantee?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
Sealant on show in Aldingbourne’s commercial buildings
Rainfall across the South East, Aldingbourne included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Aldingbourne is about 52 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.
For premises near Barnham station, which lies east of Aldingbourne, footfall is part of the plan: work is phased so shops and offices keep trading. On a business park such as The Woodhorn Business Centre (0.9 miles south-west of Aldingbourne), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Sites a few miles apart, such as The Woodhorn Business Centre and Chichester Business Park., can share one programme and one point of contact.
