Blocks and managed buildings in Felden
The planned town of Hemel Hempstead is on Felden’s doorstep. Housing was built estate by estate, which suits planned, block-by-block mastic programmes. Felden lies roughly 22 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
Landlords with units on estates such as Apsley Industrial Estate, 0.5 miles to the north-west of Felden, can bring frame, door and external mastic across several units into one programme. Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Older buildings near Felden, from historic houses such as High Elms Manor, 3.4 miles south-east of Felden, to more modest stock, need compatible products when frames are resealed.
Felden is about 2 miles south of Hemel Hempstead, in Hertfordshire. Businesses, contractors and managing agents in Felden can call on us for mastic joints.

About our mastic sealing in Felden
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. Site teams most often ask us about leaks at window and door perimeters and draught complaints from residents or tenants, across communal kitchens and washrooms, window and door perimeters on blocks and external wall and movement joints. Whoever orders the work in Felden, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Places the size of Felden usually have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Felden: questions and answers
Is Felden too small for you to travel to?
Not at all. Felden is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Apsley Industrial Estate, near Felden?
Yes. Estates, retail parks and business parks around Felden, Apsley Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
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 work can be quoted per building or as a whole.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so there are no surprises.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Broken glass or failed sealed units
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- Communal entrances and stairwells

Quoting for work in Felden
Quotes vary with the job. Expect it to depend on:
- How much existing material needs removing
- Which sealant the job calls for
- Location, for remote and island sites
- Whether the work must be split into stages
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- What the building is and how it’s used
- Your programme or deadline
- Where the site is, with the postcode
- A wide shot and a close-up of the area
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.
Why it’s worth doing now in Felden
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. In a smaller place such as Felden, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
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.
