About our facade sealing in Hatfield
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. We work on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters, and the usual reasons a site gets in touch are old perimeter mastic that has dried out and water coming in around window frames. Looking for mastic applicators who cover Hatfield? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Developers and contractors working in Hatfield want mastic that keeps pace with the build: sealing as scaffold comes down or as each floor is decorated, and snagging before handover. Send drawings and the programme and we will price to suit.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Parking and loading for town-centre jobs in Hatfield are worth mentioning when you send details. Industrial and business units usually have yard or car park space.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed
- Share the asbestos register for older buildings

Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Insist on a full cut-out when joints are renewed
- Check the asbestos register before old mastic is disturbed
- Brief window cleaners about newly sealed joints
- Note when each elevation was last resealed
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Why act early in Hatfield
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. For businesses and landlords in Hatfield, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
What you get with us
- CSCS-carded applicators
- Colours confirmed for the specified product
- Old sealant cut out, never sealed over

Surface by surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
What else we do in Hatfield
Facade sealing in Hatfield: the local picture
A number of hotels sit less than 2 miles from Hatfield. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Hatfield is about 19 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
Building work at universities like University of Hertfordshire, 0.8 miles to the south-west of Hatfield, is often timed for the summer, mastic included. Hospital estates such as One Hatfield Hospital (to the north of Hatfield) 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.
Hatfield is about 4 miles east of St Albans, in Hertfordshire. We cover commercial sites throughout Hatfield, for single jobs and planned programmes alike. Our Hertfordshire coverage takes in 371 places. Our London page has more on work in that area.
If you need facade sealing in AL10 and AL9, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Market Place, Bishop Square and Fiddle Bridge Lane, and sites on any of them can send details for a fixed quote. Hatfield sits on or close to the A414 and B197.

Hatfield: questions and answers
Is hospital work, at somewhere like One Hatfield Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Hatfield, such as Birchwood Industrial Estate?
Yes. Our area takes in Hatfield and its surroundings, with estates and business parks such as Birchwood Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do you use silicone for external joints?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you replace windows or glass?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Cost factors for facade joints
The price varies from site to site. It mainly depends on:
- How much existing material needs removing
- The site’s rules and procedures
- Access and working height
- Working within restricted access windows
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- Specification clauses that apply
- Whether the building will be occupied during the work
- How the joints are reached, and at what height
- Whether an asbestos survey exists
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Do you need facade sealing in Hatfield?
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Things that normally lead to an enquiry:
- Failed sealant on precast panel joints
- Weathered facade joints that have lost their grip
- Perimeter joints where frames meet the structure
- New sealant peeling off old mastic
For a contractor at a hotel such as Mercure Hatfield Oak Hotel, 1.2 miles to the south of Hatfield, the mastic often has to be finished before a reopening date.
