Construction mastic in Highmoor Cross, done properly
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 oversized or tapered gaps around new frames and old sealant on a refurbishment that needs stripping before new work, across cladding and panel joints, brick and block movement joints and sanitary and kitchen joints. One point of contact handles commercial sealant work in Highmoor Cross from the first photographs to the final walk-round, whether it’s one building or several.
Sites around smaller places like Highmoor Cross can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Building and refurbishing in Highmoor Cross
Highmoor Cross is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. A 2-mile radius around Highmoor Cross takes in a number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Historic houses such as Greys Court, 1.6 miles east of Highmoor Cross, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Highmoor Cross is about 5 miles north of Caversham, in Oxfordshire. We cover commercial sites throughout Highmoor Cross, whether it’s a single job or part of a planned programme.

Surface by surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we have sealed
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Window and door perimeters
- Floor and skirting junctions
- Internal decorators’ caulk
- Brick and block movement joints
- Cladding and panel joints
- Sanitary and kitchen joints
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Any access equipment needed
- The total length or number of joints
- Site requirements such as inductions and permits
- Working within restricted access windows
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Send us:
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- The product your specification calls for
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, call 01277 525 020 or send details through our quote form.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep product details for future maintenance
- Flag uneven or tapered frame gaps early
- Put any product change through the designer first
- Keep finished joints away from paint, plaster and scrapers
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. If others near Highmoor Cross need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Make sure the joints can be reached
- Confirm the product named in the specification
- Warn occupants and staff about the work
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.
Advice
Questions about Highmoor Cross
Is Highmoor Cross too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work at a site such as Vanalloys Business Park, by Highmoor Cross?
Yes, sites like Vanalloys Business Park are within our area, along with the rest of Highmoor Cross. Send details of the unit and the work through our quote form for a quick quote.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Common problems we fix in Highmoor Cross
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
These are often picked up first by site or facilities staff:
- Mastic snags holding up handover
- Internal caulk splitting as the building dries out
- Window and door perimeters that won’t pass inspection
- Frame gaps too wide for sealant alone
Units on estates such as Vanalloys Business Park (to the west of Highmoor Cross) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
