What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Approximate linear metres or a joint schedule
- A wide shot and a close-up of the area
- The type of building and who uses it
- Any dates the work must fit around
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email a schedule or drawings.
Mastic sealing for commercial buildings in Berkhamsted
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on external wall and movement joints, balcony and threshold joints and communal entrances and stairwells, and the usual reasons a site gets in touch are patchy repairs in mismatched sealant and estate-wide sealant that is simply worn out. One point of contact handles commercial sealant work in Berkhamsted from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In a town such as Berkhamsted, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. If you have more than one building in Berkhamsted, they can often be done on the same visit. Tell us when the building is open and we’ll plan to suit.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Send any specification or drawings in advance
- Move anything stored against the joints
- Send your site hours and access windows

Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Misted or failed double-glazed units
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Frames that are rotten, warped or broken
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.
Surfaces we seal
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Balcony and threshold joints

For owners and agents in Berkhamsted
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Berkhamsted lies roughly 27 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
If you’re responsible for a building such as Church of All Saints, frame and door mastic needs the same attention as any other property. For a school such as St Thomas More Roman Catholic Voluntary Aided Primary School, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like River Park Industrial Estate, less than half a mile to the north of Berkhamsted, one programme can deal with frame and external mastic across the lot.
Berkhamsted is about 5 miles west of Hemel Hempstead, in Hertfordshire. Businesses, contractors and managing agents in Berkhamsted can call on us for mastic joints. Our Hertfordshire coverage takes in 371 places. Our London page has more on work in that area.

Berkhamsted: questions and answers
Will you price a mastic programme across our Berkhamsted portfolio?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
We manage a building near Berkhamsted station. Can you help?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Why act early in Berkhamsted
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
