Construction mastic in Lancing
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. Site teams most often ask us about snag items on joints that need redoing before handover and bath and shower joints scraped during the final clean, across sanitary and kitchen joints, floor and skirting junctions and brick and block movement joints. Looking for mastic applicators who cover Lancing? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In a smaller place such as Lancing, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Facades, frames and programmes in Lancing
With the shore within about 1 mile, Lancing counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. There are several hotels within about 2 miles of Lancing. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Projects at schools like The Globe Primary Academy work to term dates, so mastic is programmed tightly. Extensions at sites like Worthing Hospital (2 miles south-west of Lancing) typically sit beside working departments, and the mastic follows strict access rules. Units on estates such as Lancing Business Park, 0.7 miles south-west of Lancing, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Common questions from Lancing clients
Could you schedule work at a campus like Northbrook College for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Will you take on work at estates like Lancing Business Park, close to Lancing?
Yes, sites like Lancing Business Park are within our area, along with the rest of Lancing. Send details of the unit and the work through our quote form for a quick quote.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What does a mastic package normally include?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
What the job involves on each surface
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. Tell us what records you need and we will confirm with the quote.
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.
Cost factors for mastic packages
These are the things that shape the price:
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- Travel to remote or island sites
- The product specified
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.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- Asbestos survey details if the building is older
- Access details, including height
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes whatever the programme allows, since the work follows the trades as areas are released, and we clear our waste as we work. Work in places the size of Lancing is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Arrange parking or a loading space
- Tell us which areas need to stay in use
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Related advice
After the work
Regular inspection catches problems early. Specifically:
- Ask cleaners to use soft cloths around fresh sealant
- Flag uneven or tapered frame gaps early
- Release areas for mastic once other trades have finished in them
- Allow flexibility for external sealing in damp or cold weather
Any damage after we’ve finished should go on the snag list right away. We can return to clear snags before handover, priced as part of the package or separately.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.
