About our mastic sealing in Barwick
For blocks and buildings in Barwick and across Hertfordshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on shopfronts below residential blocks, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is failed external movement joints and a mix of products and colours from past repairs. Whoever orders the work in Barwick, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Barwick, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Masonry that has broken away beside the joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Glazing that needs replacing
If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer before you book.

For a building around Barwick, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We inspect the joints, building by building, and record what has failed and why.

- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.

For owners and agents in Barwick
Barwick sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. Barwick lies roughly 25 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
For agents with blocks near Ware station (3.7 miles south-west of Barwick), a block-wide mastic programme deals with frames, balconies and entrances in one go. Trustees of buildings like St Mary's can bring frame and external mastic into a planned maintenance list. Property owners at sites such as Standon Business Park, 2 miles to the north of Barwick, can have mastic renewed between lettings.
Barwick is about 3 miles north-east of Ware, in Hertfordshire. We send applicators to Barwick for mastic joints. Barwick is one of 371 places in Hertfordshire on our list. London is covered too, around 25 miles from Barwick.
Anyone looking for mastic sealing in SG11 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

What the job involves on each surface
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Questions we are asked in Barwick
We manage a building near Ware station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Do you cover business parks and estates near Barwick, such as Standon Business Park?
Yes. Our area takes in Barwick and its surroundings, with estates and business parks such as Standon Business Park included. A few photos and the unit address let us price the work.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Do you cover Barwick?
Yes. We cover Barwick, and the simplest way to start is to call 01277 525 020 or send details through our quote form.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Make it easy for occupiers to report draughts
- Keep a record of when each building was resealed
- Protect low-level joints in entrances
- Avoid piecemeal callouts where you can
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Doing it in-house
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, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
