About our facade sealing in Fields End
Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. If you have old perimeter mastic that has dried out and sealant pulling away from frames or panels, we can help, whatever the surface. Searching for sealant specialists in Fields End? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Conversions of older rural buildings near smaller places such as Fields End bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Installing or repairing glazing systems
- Joints whose design needs changing by the specifier
- Damaged frames that need replacing
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Share access with other external trades
- Insist on a full cut-out when joints are renewed
- Investigate damp beside windows promptly
- Clear debris that holds water against joints
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.
Facades, frames and programmes in Fields End
Fields End sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Several hotels sit less than 2 miles from Fields End. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Work at a hotel such as Boxmoor Lodge Hotel (to the south-east of Fields End) tends to be programmed around bookings, mastic included. Extensions at sites like Hemel Hempstead Hospital, 1.9 miles east of Fields End, normally sit beside working departments, and the mastic follows strict access rules.

FAQs: Fields End
Does your area include sites such as Chancerygate Business Centre, near Fields End?
Yes. We cover Fields End and the area around it, including industrial estates, business parks and retail parks such as Chancerygate Business Centre. Photos and a short description are enough for a first look.
Can work at a site such as West Herts College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Signs you need facade sealing in Fields End
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
What tends to prompt an enquiry:
- Gaps between rainscreen or cladding panels
- Patch repairs that keep failing
- Damp patches beside frames after rain
- Perimeter sealant that has split or peeled away
School extensions, at buildings such as John F Kennedy Catholic School, normally run to the summer holidays, mastic included.
