AN INTRODUCTION / 07
Cracked mortar, damp patches or leaning sections are visible signs that brickwork needs attention. We focus on practical repairs, new wall construction and repointing that stop water ingress and restore strength and appearance. Before any work starts we explain the likely causes, material choices and how the job will interface with roofing, gutters and boundaries.
Not all visible defects mean a full rebuild. When your house, boundary or garden wall shows obvious problems, we assess what’s cosmetic and what creates real risk to the structure. Our approach identifies whether isolated brick replacement, targeted repointing or rebuilding a section is the best use of your budget. We explain compatible mortar mixes, matching bricks where possible, and when roofers or carpenters should be brought in to tackle root causes such as poor drainage.
EXPLORE THE OPTIONSOUR SERVICES / 07
Visible defects, eroded mortar or weak garden walls call for specific responses. We cover new brick wall construction, garden walls, brickwork repairs and repointing. Each job begins with a practical inspection, and we set out the recommended fix, materials and any interfaces with roofs or drainage so you know exactly what’s included and why.
Building a new boundary or structural brick wall begins with suitable foundations, chosen bricks and appropriate bond patterns, plus provision for reinforcement and drainage. We explain options for brick type, height and finishes so the finished wall performs well and sits in keeping with the property without unnecessary expense.
ENQUIRE ABOUT THIS SERVICEGarden walls need to balance appearance with moisture resistance and stability. We lay foundations to the required depth, select appropriate bricks or blocks and include drainage where soil contact or retained soil is expected. Design details—copings, movement joints and ties—are discussed so the wall endures frost and wet periods while complementing your outdoor space.
ENQUIRE ABOUT THIS SERVICEWhen bricks are cracked, displaced or mortar has failed, we assess whether isolated brick replacement or rebuilding a run is required. Repair work uses bricks of matching size and a mortar mix with the right permeability and strength to avoid creating new problems. We also check adjacent gutters and flashings, since water running onto brickwork is a frequent cause of repeat decay.
ENQUIRE ABOUT THIS SERVICEWhere mortar joints have eroded, we remove decayed mortar carefully and repoint with a mix that matches the original in composition, colour and texture. Correct repointing restores protection against water ingress and helps prevent freeze-thaw damage. We explain the extent required—partial or full repointing—and finish joints in a style that blends with the existing masonry.
ENQUIRE ABOUT THIS SERVICEOUR PROCESS / FOUR STAGES
Practical brickwork starts with inspecting visible defects and tracing causes such as poor drainage or vegetation. We describe the recommended repair route, the materials we’ll use and any coordination needed with roofing or drainage trades before committing to work, so you know what will happen on site and why.
On inspection we record defects, photograph the area and take mortar samples for testing where needed. We check for associated issues — blocked gutters, vegetation or ground contact — that commonly accelerate brick deterioration and flag if a structural engineer’s assessment looks necessary before any repair.
Repair quality depends on correct preparation: loose mortar and damaged bricks are removed, surfaces are cleaned and any vegetation cleared back. Where foundations or drainage are contributing factors, we make provisional allowances so repairs are not undermined by the original cause. Preparing correctly prevents accelerated failure after the work is done.
We carry out bricklaying, brick replacement and repointing using mortar mixes matched to the structure’s needs. Bond patterns are reproduced where required and attention to joint finish helps the repair blend visually. When work touches roofs, gutters or lintels we coordinate the sequence to avoid water running onto fresh mortar or exposed brick faces.
After masonry works we allow mortar to cure under appropriate protection, finishing with a site inspection to ensure joints are compact, aligned and weather-resistant. We issue a written scope of completed work and point out any ongoing maintenance actions you should take to protect the repaired areas from reoccurrence.
WHY CHOOSE RAPTOR / WHAT MATTERS
Ignored brick defects often get worse over time and lead to costlier repairs. Professional brickwork replaces only what’s necessary, uses compatible materials and addresses causes like trapped moisture. That approach preserves both function and appearance and reduces the chance of repeat problems.
Selecting the right brick type and mortar prevents moisture-related damage and frost spalling. We match mortar strength and permeability to existing masonry so new work moves compatibly with the old, reducing the risk of cracked joints or brick deterioration over time.
Matching brick colour, texture and joint style maintains the visual continuity of a property. We aim for sympathetic finishes where exact brick matches are unavailable, using joint profiling and mortar tinting so repairs integrate discreetly with the original masonry.
Detecting movement, widening cracks or damp stains early lets us recommend targeted fixes rather than expensive rebuilds. We explain visible warning signs and prioritise repairs that stop water ingress and limit further decay, advising structural assessment where defects suggest deeper issues.
INSIGHT / Understanding Brickwork & Masonry
Faced with cracked or crumbling brickwork, the key questions are what will last and how to stop recurrence. We focus on material compatibility, correct preparation and the practical decisions you’ll make at survey: repair now, or replace a run of bricks, and how the work interfaces with nearby roofing or drainage.
Stair-step cracks near corners, widening mortar joints or bricks that move when nudged are reliable signs of progressive deterioration. Damp patches inside walls or visible bulging point to water penetration or movement that needs investigation. Movement often appears after nearby groundworks or tree removal, so a careful check of foundations and wall ties is prudent. Photographs taken at intervals and after wet weather help judge whether a defect is active. During a survey we look beyond the visible symptom to find causes — failed gutters, blocked drainage or roots pressing into foundations are common culprits. Immediate action can be simple: repointing or isolated brick replacement in many cases, but where lean or wide cracks appear we recommend further assessment. Choosing the correct repair balances the current condition with measures that prevent recurrence; fixing a gutter or regrading soil around the base of a wall is often as important as the masonry work itself.
When mortar has eroded, replacing it with the wrong mix can harm the bricks. Older walls often used lime-based mortar which is softer and more permeable than modern cement-rich mixes; substituting a hard cement mortar can cause bricks to crack and spall. Repointing starts with carefully raking out failed joints by hand to avoid damaging brick edges, then using a mix chosen for similar compressive strength and vapour permeability. Colour and texture matching also matter—new bright joints on an aged wall look out of place and may lead to unnecessary repainting or further patch repairs. We test small areas where necessary and explain the trade-offs between exact historical matching and practical, long-lasting protection. Proper curing and protecting fresh joints from rapid drying or driving rain help the mortar achieve intended performance, so we plan works around weather without committing to strict durations.
Water is the primary long-term threat to brickwork. Trapped moisture accelerates freeze-thaw damage and deteriorates mortar, so keeping gutters clear, ensuring downpipes discharge away from walls and avoiding soil piled against brickwork are straightforward preventative steps. Vegetation such as ivy can force moisture into joints and should be managed rather than left to cling to masonry. Cleaning should be gentle—abrasive power washing erodes joints and soft brick faces. Regular inspections after severe weather help spot earlier failures: small repairs now are almost always cheaper than later rebuilds. For garden walls, we consider drainage behind the wall and whether ground pressure or root action is likely to cause movement. When defects hint at structural issues—marked lean, wide horizontal cracks or separation from adjacent materials—we advise a structural assessment so remedial measures address root causes rather than only cosmetic symptoms.

QUESTIONS / BRICKWORK & MASONRY
Below are practical answers to common questions homeowners ask before committing to masonry work. Each response explains risk, access considerations and what we look for during an enquiry to help you prepare for a survey or estimate.
ASK ANOTHER QUESTIONLook for widening cracks, loose bricks, crumbling mortar, bulging sections or damp staining on internal walls. Take photos after wet weather and from several angles to show whether defects open up or remain static. Note nearby factors like blocked gutters or soil piled against the wall—these often contribute to deterioration and should be highlighted during your enquiry.
We aim to match brick size, colour and mortar finish where possible. Exact matches for older bricks aren’t always available, but sympathetic mortar mixes, joint profiling and careful selection of replacement bricks reduce visible contrast. We’ll show you sample patches or mock-ups where colour matching is critical before proceeding with larger work.
Not always. Minor joint loss or hairline cracks can sometimes be treated with localised repairs or crack stitching. Widespread joint failure usually merits repointing. During a survey we assess joint depth and brick condition to recommend either targeted patches or full repointing for the most durable and cost-effective outcome.
Yes—we construct new garden and boundary walls with appropriately designed foundations, drainage and coping. We discuss brick choice, height, required ties or reinforcement and any neighbour access implications during the survey so the finished wall meets functional needs without unexpected site issues.
Consider a structural assessment if a wall shows marked lean, large stair-step cracks, separation from adjoining structures or if movement appeared after significant groundworks. A structural specialist can identify foundation or settlement issues; we’ll flag these concerns during our inspection and recommend professional assessment before carrying out major repairs.
For a survey provide safe access to the affected area and clear any plants or stored items that obstruct inspection. For repairs we may need scaffold or ladders depending on height, and clear ground space for materials. We detail access and site preparation requirements in our pre-work notes after the initial assessment so you can arrange any neighbour access or clearance needed.
