Building using Northcot Brick Handmade Bricks

Handmade Bricks Q&As

Below are a selection of questions and answers in the Handmade Brick manufacturing process.

If you cannot find the answer to your brick manufacturing question please contact our friendly team on 01386 700551 and they will be happy to answer any questions you have.


Question:
What makes your bricks 'handmade,' and how does this affect the look?

Answer:
Our handmade bricks are genuinely hand-molded using the traditional 'soft mud' method. A craftsman 'throws' the clay into a sanded wooden mould. This process results in a creased, characterful face, softer edges, and slight variations in size and shape that are impossible to replicate with machinery.


Question:
How do you achieve your unique range of handmade brick colours and textures?

Answer:
Our handmade brick colours are primarily achieved through the natural mineral content of our clay (e.g., iron oxide for reds) and the precise control of oxygen and temperature in the kiln (the 'firing atmosphere'). Texture comes from the hand-molding process and the type of sand used to line the mould.


Question:
Why is there a variation in size and colour between individual handmade bricks?

Answer:
This variation is the hallmark of authentic handmade bricks and gives the finished wall its unique aesthetic depth. It's due to the individual crafting of each unit and the natural temperature fluctuations in the kiln. We advise blending bricks from multiple packs on site for a harmonious appearance.


Question:
How does mortar choice impact the final aesthetic of your handmade bricks?

Answer:
Mortar colour and joint profile are just as important as the handmade bricks themself. A light, often traditional lime-based mortar enhances the texture, while a darker mortar can make the colour of the handmade bricks appear richer and more dominant. We strongly recommend building a sample panel.


Question:
Are your handmade bricks suitable for use in conservation areas or on heritage projects?

Answer:
Yes. Our handmade bricks are specifically sought after for these projects because they are made using traditional methods and often match the imperial sizes and unique characteristics of historic masonry, satisfying strict planning requirements for authenticity.


Question:
Do your handmade bricks meet the required standards for durability and frost resistance?

Answer:
Absolutely. All our facing bricks are manufactured to rigorous national standards (e.g., BS EN 771-1 in the UK). We provide data sheets confirming they achieve the highest Frost Resistance rating (F2) and low Soluble Salt Content (S2), making all our handmade bricks suitable for severe weather exposure.


Question:
What are the typical Water Absorption and Compressive Strength figures of handmade bricks?

Answer:
Our technical data sheets provide precise figures, but generally, handmade bricks have a moderately higher water absorption than extruded bricks (often between 12-18%), which is a natural result of the process. Compressive Strength is typically robust and suitable for most load-bearing applications.


Question:
What is the dimensional tolerance on your handmade bricks?

Answer:
Due to the nature of hand-molding, our handmade bricks have a dimensional tolerance in line with the standards for traditionally made units. While they are consistent to a pattern, site preparation and laying techniques (using a wider joint) must accommodate for the natural, charming variations.


Question:
How do you ensure long-term colour fastness and resistance to fading on handmade bricks?

Answer:
The colour is permanently 'locked in' during the high temperature firing process, as it is a natural chemical reaction of the clay's mineral content. Unlike surface treatments, the colour runs all the way through the handmade bricks, guaranteeing colour fastness for the lifetime of the structure.


Question:
What steps are necessary to prevent efflorescence on handmade bricks (salt deposits)?

Answer:
Efflorescence is primarily caused by soluble salts within the wall being drawn to the surface by moisture. In our handmade bricks, we adhere to low soluble salt content (S2). Prevention requires good building practice—keeping bricks dry on site, using clean water and sand in the mortar, and ensuring proper DPC and coping.


Question:
Can you match an existing brick on an older property with your new handmade bricks?

Answer:
Yes, our brick matching service is a core specialty. We analyze a sample brick for size, colour, texture, and firing technique. Our custom molds and bespoke clay blends allow us to replicate historic handmade bricks for seamless extension or restoration work.


Question:
Do you offer special shape handmade bricks (e.g., radial, arch, cant bricks)?

Answer:
Absolutely. This is another major benefit of handmade brick production. We can create a full range of traditional and bespoke special shapes to meet your architectural detailing requirements for arches, corbeling, plinths, and unique window details.


Question:
 
What is the typical lead time for an order of your handmade bricks?

Answer:
Lead times can vary depending on product availability and whether the handmade brick is a stock item or a custom run. Standard stock items may take 2-4 weeks, while a bespoke order can take 8-16 weeks. We will provide a precise, confirmed lead time at the time of quotation.


Question:
How do you ensure handmade bricks are laid correctly to achieve the best result?

Answer:
We provide detailed laying instructions and recommend using skilled bricklayers who are experienced with handmade brick products. The key steps are blending bricks from multiple packs, accommodating the size variation with the mortar joint, and laying cleanly to avoid mortar smears.


Question:
How should the handmade bricks be stored on site?

Answer:
Handmade bricks must be kept clean and dry. They should be stored on a hard, clean surface, covered with waterproof sheeting, and protected from contaminants, especially in winter or during inclement weather.


Question:
Are handmade bricks considered a sustainable/eco-friendly building material?

Answer:
Yes. Our handmade bricks are made from abundant, naturally occurring clay and, crucially, are renowned for their exceptional longevity (lasting centuries). Furthermore, modern kilns, even for traditional bricks, are designed for high energy efficiency, and we prioritise local sourcing of materials to minimise transport emissions.


Question:
What is your recommendation for estimating waste when using handmade bricks?

Answer:
Due to their nature, some wastage can occur from breakages or cutting on site. We advise customers to factor in a 5% to 10% waste allowance when calculating the final quantity of handmade bricks to ensure the project does not run short.
