FAQs: Upper Wellingham
Will you take on work at estates like Diplocks industrial estate, close to Upper Wellingham?
Yes, sites like Diplocks industrial estate are within our area, along with the rest of Upper Wellingham. Photos and a short description are enough for a first look.
Could you schedule work at a campus like University of Sussex for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
What guarantee comes with a mastic package?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we have finished isn’t covered.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes whatever the programme allows, since the work follows the trades as areas are released. For bigger or phased jobs, we’ll set out a timescale with the quote.

Construction mastic for commercial buildings in Upper Wellingham
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Site teams most often ask us about external joints sealed in damp or cold conditions that are now failing and frame perimeters left unsealed or poorly sealed, across internal decorators’ caulk, brick and block movement joints and sanitary and kitchen joints. Whoever orders the work in Upper Wellingham, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What the job involves on each surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.

After the work
After handover, a little attention goes a long way:
- Bring the mastic contractor in after the last trades are through
- Plan external elevations with the weather in mind
- Flag uneven or tapered frame gaps early
- Stick to the specified sealant rather than a generic substitute
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That typically means redoing finishes in a completed area, and a delay to handover. A check of every frame before decorators start is worth the time.
Building and refurbishing in Upper Wellingham
Upper Wellingham is about 41 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Upper Wellingham sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
Units on estates such as Diplocks industrial estate, 1.1 miles south-east of Upper Wellingham, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. School extensions, at buildings such as Ringmer Community College and Sixth Form, typically run to the summer holidays, mastic included. Extensions at sites like Lewes Victoria Hospital (to the south-west of Upper Wellingham) typically sit beside working departments, and the mastic follows strict access rules.

What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Joints damaged after sign-off by following trades
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.
