How we handle construction mastic in Postling Green
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short. We work on brick and block movement joints, cladding and panel joints and window and door perimeters, and the usual reasons a site gets in touch are old sealant on a refurbishment that needs stripping before new work and bath and shower joints scraped during the final clean. Looking for mastic applicators who cover Postling Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Conversions of older rural buildings near smaller places such as Postling Green bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Surface by surface
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps, and we will tell you if the detail calls for something else. Record requirements are agreed with the quote.
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, normally a low-modulus neutral-cure silicone and set the depth with backing where needed.
Do you need construction mastic in Postling Green?
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
Typical triggers for a call:
- Different trades sealing to different standards
- External joints sealed in damp or cold conditions that are now failing
- Failed sealant in an existing building being refurbished
- Cracks opening in caulked internal joints
With historic properties like Westenhanger Castle, 3.2 miles east of Postling Green, in the area, refurbishment work often meets old masonry that needs compatible sealants.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Who will actually carry out the work

- Glazing units that are cracked or misted

Quoting for work in Postling Green
Quotes vary with the job. Expect it to depend on:
- Backing rod, priming and other preparation
- Any access equipment needed
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Access details, including height
- Approximate linear metres or a joint schedule
- When you need the work done
- The product your specification calls for
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email the details over.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. 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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.
