Construction mastic for commercial buildings in Falmer
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Falmer, send drawings and the specification through our quote form. Site teams most often ask us about snag items on joints that need redoing before handover and cracks opening in caulked internal joints, on floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk. For commercial sealant work in Falmer, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around smaller places like Falmer, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: Falmer
Could you schedule work at a campus like University of Sussex for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you take on work at estates like Fairway Industrial Estate, close to Falmer?
Yes. Estates, retail parks and business parks around Falmer, Fairway Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can you quote from photographs?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Falmer need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.

Getting a fixed quote

Advice
Quoting for work in Falmer
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Phasing around occupants
- The size and state of each joint
- Quantities, in metres or numbers
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
We can often quote from photos and a few details. Please tell us:
- How the joints are reached, and at what height
- Specification clauses that apply
- When you need the work done
- Asbestos survey details if the building is older
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.

What else we do in Falmer
Why it’s worth doing now in Falmer
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we will say so. Around Falmer, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Mastic packages on Falmer sites
Falmer is about 44 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Falmer is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
When a school such as Brighton Aldridge Community Academy is extended or refurbished, the mastic package is often squeezed into the holidays. University estates such as University of Sussex (under half a mile north-west of Falmer) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Falmer is about 3 miles north-east of Brighton, in East Sussex. We send applicators to Falmer for mastic packages. Falmer is one of 308 places we cover in East Sussex for mastic packages.
Anyone looking for construction mastic in BN1 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Landmarks near Falmer

For a walk, there’s Bevendean Down and Newmarket Hill.
Surface by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies, and seal only with a dry joint inside the product’s temperature range.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.
Common problems we fix in Falmer
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.
Clients normally get in touch after noticing one or more of the following:
- Inconsistent sealant finishes from plot to plot
- Early adhesion failures on new external joints
- Internal caulk splitting as the building dries out
- Perimeter gaps outside the sealant’s range
For contractors at a college like Downs View Link College, 2.9 miles to the west of Falmer, perimeters and internal sealant are timed for the holidays.
Questions to ask before you book
- How long is the guarantee, and what does it include?

- How the existing material will be dealt with
