Cost factors for mastic packages
A fixed quote reflects the actual work. It takes account of:
- Whether the work must be split into stages
- Location, for remote and island sites
- Site requirements such as inductions and permits
- How much there is to seal
Pricing mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Anything awkward about access or site hours
- Any specification or named product
- Whether the building will be occupied during the work
- When you need the work done
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or email a schedule or drawings.
About our construction mastic in Wytham
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. We work on brick and block movement joints, window and door perimeters and sanitary and kitchen joints, and the failures we are asked to look at most are external joints sealed in damp or cold conditions that are now failing and old sealant on a refurbishment that needs stripping before new work. Whoever orders the work in Wytham, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Wytham is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Wytham
Is Wytham too small for you to travel to?
No. Places such as Wytham are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is hospital work, at somewhere like Radcliffe Infirmary, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you come in just for snagging?
Yes. We can work through a mastic snag list area by area before handover, cutting out damaged or poor joints and resealing them.
Can the building stay open while you work?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Surface by surface
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For work around Wytham, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- 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.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Explain the parking and delivery arrangements
- Let building users know which areas are affected
- Tell us your opening times and when work is allowed

Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Do you need construction mastic in Wytham?
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Most enquiries start with one or more of the following:
- Early adhesion failures on new external joints
- Sanitary sealant damaged by following trades
- Old sealant on a refurbishment that needs stripping before new work
- Caulk cracking where joints are moving more than expected
New units and refits on sites such as Seacourt Retail Park, 1.7 miles to the south-east of Wytham, need their panel and perimeter joints sealed to the specification.
What your quote should include
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
