Mastic sealing for businesses in Eastergate
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Mastic sealing in Eastergate
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Eastergate carry our 12-month guarantee. If you’re dealing with open joints in brickwork or panels and occupiers reporting cold air round windows, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Eastergate is the same: the right product in a properly prepared joint.
Owners and agents with buildings around smaller places such as Eastergate tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for mastic joints
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Whether the work must be split into stages
- Site requirements such as inductions and permits
- How accessible the joints are
- Joint width, depth and condition
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- When you need the work done
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
- Anything awkward about access or site hours
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or send details through our quote form to discuss it first.
Different surfaces, different methods
Planned maintenance
Planned resealing replaces emergency callouts and spreads the work.
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Leaks through the frame itself rather than the perimeter
- Misted or failed double-glazed units
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.
Surfaces we seal
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Window and door perimeters on blocks
Block-wide mastic in Eastergate
Eastergate has six care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents. Eastergate lies roughly 52 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Schools and community buildings such as Eastergate CofE Primary School need frame and external mastic kept sound like any building. Landlords with units on estates such as Sussex Business Village, 1.7 miles to the east of Eastergate, can bring frame, door and external mastic across several units into one programme.

Do you do block-wide mastic programmes?

Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you work in Eastergate?
Yes. We take on work across Eastergate, and the same phone number covers every area.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Common problems we fix in Eastergate
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
Look out for the following:
- Patchy repairs in mismatched sealant
- Brittle perimeter mastic across a building
- Complaints coming in block by block
- Damaged joints in communal entrances and corridors
Student accommodation around universities such as University of Chichester, 3.1 miles to the south-west of Eastergate, is typically managed block by block, which suits a planned mastic programme.
