Quoting for work in South Malling
There’s no standard rate for sealant work, because every site is different. What we look at:
- Removal of failed or old sealant
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The product your specification calls for
- A wide shot and a close-up of the area
- Any dates the work must fit around
- The type of building and who uses it
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
About our construction mastic in South Malling
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. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. Most enquiries involve bath and shower joints scraped during the final clean and failed sealant in an existing building being refurbished, across cladding and panel joints, sanitary and kitchen joints and floor and skirting junctions. Searching for sealant specialists in South Malling? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Building work in places the size of South Malling is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. 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. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Keep product details for future maintenance
- Release areas for mastic once other trades have finished in them
- Flag uneven or tapered frame gaps early
- Brief following trades on areas that have been sealed
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
What else we do in South Malling

Do you cover business parks and estates near South Malling, such as Riverside Industrial Estate?

Would you work within a site like Lewes Victoria Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can fire-rated sealing at service penetrations be included?
Where it’s specified, yes to the tested detail. We will flag if the detail needs a different product.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in South Malling, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Drawings, the sealant specification and your programme come to us for pricing.

Surface by surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we’ll confirm with the quote.
What happens if it’s left?
Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. We cut out and redo the joint properly. In a smaller place such as South Malling, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Mastic packages on South Malling sites
A 2-mile radius around South Malling takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. South Malling lies roughly 43 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
