Mastic sealing for commercial buildings in Hinxworth
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you are dealing with draughts at frames across a block and patchy repairs in mismatched sealant, we can put it right. Looking for mastic applicators who cover Hinxworth? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Hinxworth, 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.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Hinxworth are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work
- Send your site hours and access windows

Advice
Leave it or put it right?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Hinxworth, rather than one at a time. Send photographs of each area and we will quote for the lot.
Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

Planned mastic for Hinxworth portfolios
Hinxworth is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. At about 38 miles from central London, Hinxworth is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
Property owners at sites such as Stratton Business Park, 2.2 miles to the north-west of Hinxworth, can have mastic renewed between lettings. Older community buildings, Church of St Nicholas among them, often have frames of mixed ages whose mastic varies.

Hinxworth: questions and answers
Will you take on work at estates like Stratton Business Park, close to Hinxworth?
Yes. Our area takes in Hinxworth and its surroundings, with estates and business parks such as Stratton Business Park included. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Hinxworth too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Signs you need mastic sealing in Hinxworth
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.
Typical triggers for a call:
- Water getting in round frames after rain
- Occupiers reporting cold air round windows
- No planned programme for sealant
- Cracked, hardened mastic round windows on a block
For agents with blocks near Arlesey station, 3.3 miles to the south-west of Hinxworth, a block-wide mastic programme deals with frames, balconies and entrances in one go.

- How long is the guarantee, and what does it include?
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Failed window or door frames, which need a window contractor
- Masonry that has broken away beside the joint
- Water coming in from the roof or rainwater goods
If you’re not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.
