Construction mastic for businesses in Platt's Heath
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What sets the cost
Before we quote, we look at:
- Access and working height
- Quantities, in metres or numbers
- The size and state of each joint
- The product specified
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- The site address and postcode
- When you need the work done
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’ll arrange a site visit if anything is unclear.
Construction mastic in Platt's Heath, done properly
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. Site teams most often ask us about missed perimeter joints on a new elevation and old sealant on a refurbishment that needs stripping before new work, across brick and block movement joints, sanitary and kitchen joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Platt's Heath, preparation and product choice get the time they need.
In the countryside around places like Platt's Heath, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Why act early in Platt's Heath
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. For buildings around smaller places like Platt's Heath, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
Why us?
- A range of standard colours, depending on the product
- Work carried out by CSCS-carded applicators
- RAL and finish matching where the product range allows
- Constructionline member for supplier checks

Advice
Signs you need construction mastic in Platt's Heath
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
It’s worth sending us details if you spot any of the following:
- Missed perimeter joints on a new elevation
- Different trades sealing to different standards
- Cracks opening in caulked internal joints
- New external sealant already peeling away
Historic houses such as Leeds Castle, 3 miles to the north-west of Platt's Heath, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
What joints do you seal on a new build?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens in one fixed quote.
How do you work with the site programme?
