Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Surface by surface
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit.
Construction mastic for commercial buildings in Chichester
The specification and the programme set the job, not to habit. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. We work on cladding and panel joints, window and door perimeters and internal decorators’ caulk, and the usual reasons a site gets in touch are failed sealant in an existing building being refurbished and cracks opening in caulked internal joints. For commercial sealant work in Chichester, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Older town-centre buildings in places like Chichester are often converted to new uses or extended, so new windows and cladding meet old masonry. Getting the product and primer right for both faces is what keeps those joints sound.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building owners, agents and FMs in Chichester
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Chichester can sit alongside others in a wider programme across West Sussex.
What we’re called out for in Chichester
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is usually the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
Things that typically lead to an enquiry:
- Sanitary sealant damaged by following trades
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
- New external sealant already peeling away
Building work at universities like University of Chichester (to the north-east of Chichester) is often timed for the summer, mastic included.
Comparing quotes
- Whether primer will be used where the manufacturer specifies it
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
Chichester: questions and answers
Would you work within a site like St Richard's Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will you plan work around the academic year at somewhere like University of Chichester?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on mastic snagging only?
Yes. We clear snags by redoing joints rather than patching them.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Do you work in Chichester?
Yes. Chichester falls within our area, and you can speak to us on 01277 525 020 or send details through our quote form to get started.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
What guarantee comes with a mastic package?
The work is guaranteed for 12 months, covering how we sealed. Protecting sealed areas from following trades helps avoid damage.
Quoting for work in Chichester
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- How much there is to seal
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
Pricing mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.
What we need to price the job
To price the job accurately, we need to understand the site. Send us:
- The asbestos register, for older buildings
- Your programme or deadline
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or use the quote form if you’d rather talk the job through.
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Specifying the product where the designer hasn’t
- Damage to finishes by other trades after we’ve sealed
- Glazing units that are cracked or misted
If you’re not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
What we seal
- Window and door perimeters
- Floor and skirting junctions
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Brick and block movement joints
- Cladding and panel joints
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If you have more than one building in Chichester, they can often be done on the same visit. Tell us when the building is open and we will plan to suit.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Arrange parking or a loading space
- Let us know about inductions and permits
- Send your site hours and access windows
Quotes
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or send photos by email.
Advice
New build and refits around Chichester
Central London is about 54 miles from Chichester. 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. A 2-mile radius around Chichester takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Further education sites such as Chichester College (to the south-west of Chichester) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hospital estates such as St Richard's Hospital (0.5 miles north-east of Chichester) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Chichester is about 27 miles east of Southampton, in West Sussex. We cover Chichester and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else.
