If you own a property in Grantham, chances are you’ve thought about what it could become with the right renovation work behind it. Building renovations in Grantham is what we do every single day, and we’ve been doing it since 1992. From Victorian terraces on Harlaxton Road to post-war semis, interwar bungalows, and Georgian townhouses closer to the town centre, Grantham’s housing stock varies dramatically. That variety matters because no two renovations are the same, and a contractor who treats them as if they are will get you into trouble fast.
We’ve worked on properties across Grantham for over 30 years, and we know the quirks that come with the territory. Older properties in areas like Earlesfield and Dysart Road often have solid brick construction with lime mortar pointing that needs like-for-like replacement, not modern cement repointing which causes damp problems down the line. Some of the older stock around St Wulfram’s Church has original sash windows and timber joinery that deserves careful restoration rather than rip-out-and-replace. These are the kinds of details that separate a competent building renovation from a botched one, and they’re the details we never overlook.
A building renovation can cover an enormous range of work. It might mean stripping a property back to brick and starting again with insulation, new first fix electrics and plumbing, plastering, and full internal fitout. Or it might be more surgical: replacing a failing flat roof, underpinning a subsiding foundation, re-configuring internal walls to create open-plan living, or finally sorting out that damp issue that’s been lingering for years. We plan every job properly before a single tool comes out, because that’s how you avoid costly surprises mid-project. If you’d like to talk through what your property needs, get in touch with our team and we’ll arrange a site visit at a time that suits you.
Whatever the scale of your renovation, you deserve a contractor who’s honest about what’s involved, realistic about timescales, and capable of delivering the finished result you’re after. We don’t oversell or underquote. We give you a clear picture of the work, the cost, and how long it’ll take, then we get on with it.
Grantham is a market town with centuries of building history behind it. That’s exciting from a renovation standpoint, but it also means you need to know what you’re dealing with. A large proportion of the residential properties in and around Grantham predate cavity wall construction, which became standard in the 1930s. Solid wall properties require a completely different approach to insulation, damp-proofing, and structural repair than modern builds. If you try to apply modern techniques to an 1890s brick terrace without understanding the building’s original logic, you’ll create condensation problems, damp ingress, and potentially structural issues within a few years.
We always carry out a proper pre-renovation assessment on older properties. This typically involves checking the condition of the existing damp-proof course (or identifying whether one exists at all), assessing the state of the original joists and floor structure, checking for lead pipework, asbestos-containing materials in artex ceilings or floor tiles, and evaluating the structural integrity of any chimney breast or party wall before any alteration work begins. For listed buildings or properties within a conservation area near Grantham town centre, permitted development rights are often restricted, so we’ll identify early on what requires formal planning consent and what falls under building regulations only.
One of the most common renovation scenarios we handle in Grantham is the full internal reconfiguration. Homeowners who’ve bought a tired 1930s or 1950s semi want to open up the kitchen and dining room, perhaps remove a chimney breast to gain floor space, and modernise the bathrooms throughout. This kind of work involves structural calculations for any load-bearing wall removal, steel beam installation, new flooring substrates, full replastering with bonding coat and finish plaster, and first and second fix work throughout. It’s involved, but the transformation is significant. If you’re also thinking about updating your interiors alongside the structural work, take a look at our home improvements Grantham service, which covers the finishing trades in detail.
Commercially, we also handle renovation work on retail units, offices, and light industrial premises across Grantham. The considerations are different: fire door compliance, Part B building regulations for means of escape, asbestos management plans, and the need to maintain some level of business operation during the works. We’ve managed all of that, and we understand that commercial renovations need a clear programme of works from day one.
We don’t just operate in Grantham; we cover a vast area of the Rutland area. Below is a list of our high volume locations:
There’s a real difference between patching problems and genuinely renovating a property. A lot of Grantham homeowners come to us having spent years putting sticking plasters on ageing buildings: re-rendering over damp that hasn’t been properly treated, covering old floorboards with laminate that’s now lifting, painting over cracks that have returned within months. The honest answer in most of those cases is that a proper renovation, done once and done right, is cheaper in the long run than a cycle of minor repairs that never actually fix the underlying issue.
When a renovation is properly planned and executed, the changes to daily life are immediate and lasting. Homes that were cold and draughty because of inadequate insulation and single-glazed timber windows become warm and energy-efficient. Layouts that felt cramped and awkward because they were designed for a 1950s way of living get opened up to suit how people actually use space today. Bathrooms that were a source of daily frustration become functional, attractive rooms. These aren’t cosmetic changes; they’re fundamental improvements to how a building performs and how comfortable it is to live in.
Grantham’s property market also rewards well-renovated homes. Buyers in this area are discerning, and the difference between a property that’s been thoughtfully renovated with quality materials and one that’s been done on the cheap is obvious to any experienced surveyor or buyer. If you’re renovating with a view to selling within five years, we’d encourage you to think about the choices that add real value: solid hardwood or engineered oak flooring rather than laminate, porcelain tiling in bathrooms rather than ceramic, proper plastered walls rather than dry-lining everywhere. We’ll always give you honest advice on where to spend and where you can save without compromising the result.
One project that gives a good sense of what we do was a full renovation of a detached 1960s property on the south side of Grantham. The owners had bought it knowing it needed significant work: the flat roof over the rear extension was failing (it had an old felt system that had bubbled and cracked beyond repair), the kitchen was original and beyond saving, the bathroom suite dated from the 1980s, and the main bedroom had a damp issue caused by a failed cavity tray above a window lintel. We started with the roof, replacing the old felt with a modern GRP fibreglass system with a proper perimeter trim detail to prevent future water ingress. Once the envelope was watertight, we addressed the lintel, repointed the exterior brickwork where needed, and then moved inside. The kitchen was stripped back to blockwork, new insulation was installed to the external walls, and a full refit followed. The finished project took fourteen weeks and gave the owners a property that was essentially rebuilt to a modern standard while keeping its original character.
A quite different example was a commercial renovation in Grantham town centre: a former retail unit being converted for office use. The ground floor had an existing suspended timber floor that had partially collapsed due to dry rot in the joists, so that came out completely and was replaced with a beam and block floor with underfloor insulation to meet current Part L building regulations. We installed a new suspended ceiling grid throughout with recessed LED lighting, new partitioning to create meeting rooms and a reception area, and a full redecoration. The work was carried out over eight weeks while the tenant above remained in occupation, which required careful noise management and a strict programme to keep disruption to an absolute minimum.
Both of those examples show something important: renovation work is rarely straightforward, and the ability to problem-solve on site, adapt to what you find behind walls and under floors, and keep the project moving without cutting corners is what separates experienced contractors from less seasoned ones. Thirty years of this kind of work in and around Grantham means we’ve seen most of what a building can throw at you, and we know how to handle it properly.
The most tangible benefit of a properly executed building renovation is improved thermal performance. Grantham winters can be biting, and older properties without adequate wall insulation, roof insulation to current standards (270mm of mineral wool in a loft, ideally), and modern double or triple glazing are expensive to heat. Post-renovation energy bills in properties we’ve worked on have dropped significantly, partly because of better insulation but also because modern boiler installations and controlled ventilation systems work far more efficiently than the heating setups in many older Grantham homes.
Structural soundness is another benefit that’s easy to underestimate until something goes wrong. Sorted early, issues like foundation movement (common in areas of Grantham built on clay subsoil), failing lintels over window and door openings, and deteriorating party walls are manageable. Left alone, they become very expensive and in some cases dangerous. A renovation gives you the opportunity to identify and resolve these issues before they become critical, and it gives you the peace of mind of knowing the building has been properly assessed by people who understand construction, not just decoration.
From a financial perspective, a renovated property in Grantham gathers a meaningfully higher sale price and rental yield than an unrenovated equivalent. It also attracts a better quality of buyer or tenant. But beyond the numbers, the less-talked-about benefit is simply that you enjoy your home more. A well-renovated property that’s warm, well-lit, properly laid out and finished to a decent standard is a pleasure to live in. That’s the outcome we’re always aiming for, and it’s the measure by which we judge whether a project has been a success.
Building renovations is a broad term, and it’s worth being clear about what it actually covers. At the structural end, we handle foundation repairs and underpinning, load-bearing wall removal with steel beam installation (RSJs or steel goal posts depending on the span and load), chimney breast removal and retention, party wall works carried out in compliance with the Party Wall etc. Act 1996, and full roof replacements or repairs using materials appropriate to the existing building, whether that’s natural slate, concrete or clay plain tiles, GRP flat roofing, or EPDM rubber membrane systems for larger flat roof areas.
Internally, our renovation services cover full strip-out and first fix work, which includes new stud or block internal partitions, first fix carpentry for joists and stud frames, first fix electrics (consumer unit, ring mains, lighting circuits), first fix plumbing for heating, hot and cold water, and drainage. We then carry out plastering, screeding of floors where required, second fix carpentry including door linings, architraves, skirting, staircase work and built-in joinery, second fix electrics and plumbing, and final decoration. The full package, managed by one contractor who’s responsible for all of it, is far less stressful than trying to coordinate multiple trades yourself and hoping they all turn up when they’re supposed to.
For external renovations, we carry out repointing (traditional lime mortar for pre-1920s properties, sand and cement for later stock), render repairs and full re-rendering, masonry cleaning, window replacement (we work with timber, aluminium, and uPVC frames depending on the property type and any planning constraints), and external insulation systems where appropriate. We’re also experienced in heritage repair techniques for older Grantham properties where the original character needs to be preserved alongside the practical improvements. Whatever combination of services your renovation requires, we’ll put together a clear, itemised specification so you know exactly what’s included.
Not always. Many loft conversions fall under permitted development, but it depends on your property and the size of the build. We’ll check all regulations and handle applications if required.
Construction Interior Design Ltd has been operating since 1992, which means over 30 years of hands-on renovation and construction work across Grantham and the wider East Midlands.

Our team holds CSCS cards as a baseline, with additional accreditations including IPAF for powered access work, PASMA for mobile scaffold towers, and SSSTS site supervisor certification, which means our projects are run to a proper safety standard, not just a loose estimate of what’s safe enough.
We’ve worked on major commercial contracts alongside Simons Construction and Simpson Shopfitting, which gives us experience of delivering to tight programmes, precise specifications, and the high standards that main contractors demand. That discipline carries into every residential renovation we carry out in Grantham. We don’t have one standard for commercial work and a lower one for private clients. The same rigour, the same quality of materials, the same attention to detail applies regardless of the size or type of project.
The honest truth is that the renovation market in Grantham has no shortage of contractors. What it does have a shortage of is contractors who’ve been around long enough to stand behind their work with genuine credibility, who hold the right accreditations, and who communicate honestly throughout a project rather than going quiet when problems arise. We’re proud of the reputation we’ve built over three decades, and every project we take on is an opportunity to reinforce it.
