Builders in Harrow
Looking for reliable builders in Harrow? EDDI Construction Ltd is a family-run firm covering everything from small repairs to full renovations across Harrow and the surrounding NW London area — one trusted team for every job around the house.
Call +44 7492 350404We save you the hassle of chasing separate contractors. Our team covers plumbing, tiling, plastering, carpentry, painting, flooring, brickwork and full kitchen, bathroom, extension and loft work — so one call gets your whole project moving.
Good building work is as much about how it is done as what is done. We work cleanly, protect your home, and finish to a standard we are happy to put our name to. That care is why so much of our Harrow work comes from word of mouth.
Harrow grew outwards along the Metropolitan line, and the housing reflects it — street after street of inter-war bay-fronted semis through North Harrow, South Harrow and Rayners Lane, older Victorian terraces around Wealdstone, and larger detached houses up towards Harrow-on-the-Hill. Older properties come with predictable jobs: render and pointing to make good, dated kitchens and bathrooms in otherwise sound houses, and roof, gutter and fascia work on steep pitched roofs.
Deep rear gardens and generous roof space make much of Harrow well suited to adding room without moving. We take on loft conversions, rear and side-return extensions and full refurbishments, managing every trade so you deal with one team from the first quote through to the final finish.
No surprises and no pressure — you get an itemised quote before any work begins, and we stick to it. Whether it is a day's repair or a months-long renovation, you always know where you stand.
Not every Harrow street is treated the same by the council, and it is worth knowing which one you are on before planning work. There are conservation areas around Harrow-on-the-Hill and pockets elsewhere in the borough where changes to the front of a property — windows, doors, roof coverings, front boundary walls, render finishes — are looked at far more closely than they would be a mile away, and where permitted development rights are restricted or removed altogether. That does not mean you cannot do the work. It means the specification and the approvals need thinking about at the start rather than being discovered halfway through. We will tell you plainly at quote stage whether your property is likely to be affected and what that changes about the job, rather than pricing a scheme that will not get consent.
A large share of what we do on older Harrow property is not glamorous and is worth more than most of the work that is. Failed pointing lets water into the wall behind it. Cracked or blown render traps that water rather than shedding it, which is why patching over a blown section usually makes things worse. Blocked or sagging gutters put a steady run of water down a wall for years. Steep pitched roofs on the inter-war semis shed water fast, which is fine until a gutter cannot take the volume or a fascia has softened. These are the jobs that quietly protect everything inside the house, and they cost a fraction of dealing with the damp, timber decay and internal damage that follows when they are left. We are happy to look at the outside of a property and tell you honestly what needs doing now and what can wait a season.

Yes — call or message us for a free, no-obligation quote with clear pricing.
Yes. As well as Harrow we work across Wealdstone, North Harrow, South Harrow, Rayners Lane, Harrow Weald, Stanmore, Edgware and Wembley.
Yes. Parts of Harrow are Victorian and Edwardian, and we are experienced with older pipework, plaster and brickwork as well as modern installations.
In most cases yes, but the specification and approvals need settling at the start. Conservation areas around Harrow-on-the-Hill and elsewhere in the borough restrict changes to windows, doors, roof coverings, render and front boundary walls, and can remove permitted development rights. We will tell you at quote stage whether yours is likely to be affected.
Yes, and on older Harrow property it is some of the most valuable work we do. Failed pointing and cracked render let water into the wall rather than shedding it. Patching over a blown section usually makes it worse — we cut back to sound material and make good properly.
Yes. Blocked or sagging gutters run water down a wall for years and cause far more damage than their repair costs. We clear, repair and replace guttering, fascias and soffits, which on the steep pitched roofs common across Harrow is worth staying on top of.
All over the borough — North Harrow, South Harrow, Rayners Lane and Wealdstone are the most frequent, along with Harrow Weald and the streets up towards Harrow-on-the-Hill. We also cover neighbouring Stanmore, Edgware and Wembley.
