If you have ever hired a painter, gypsum installer, or waterproofing team in Nairobi and ended up with peeling walls, a leaking roof, or a contractor who vanished after the deposit — this guide is for you.

Kenya's home improvement industry is booming. More homeowners and businesses are renovating, expanding, and upgrading their spaces. But with growth comes risk: the market is crowded with underqualified contractors who underquote, overcharge, and underdeliver.

What Services Count as Home or Office Improvement?

Before we talk about hiring, it helps to understand the full scope of what a professional improvement contractor handles. A full-service provider covers:

Each service requires different materials, skills, and timelines. A contractor who claims to do all of them at suspiciously low rates should raise a flag.

Why Your Choice of Contractor Matters So Much

Poor workmanship on a home improvement project is not just an aesthetic problem — it is a financial one. Here is what bad contracting actually costs you:

Peeling Paint Within 12 Months

Cheap contractors use low-grade paint or skip surface preparation — sanding, priming, filling cracks. You end up repainting within a year, doubling your total cost.

Gypsum Ceilings That Sag or Crack

Incorrect framing, wrong spacing, or poor moisture management causes gypsum boards to fail — sometimes dangerously. A professional team uses moisture-resistant boards in wet areas and correctly spaced metal profile framing throughout.

Epoxy Floors That Peel or Bubble

Epoxy application requires precise floor preparation — grinding, moisture testing, and priming. Skipping steps causes delamination within months. A properly applied epoxy floor lasts 10–20 years.

Waterproofing That Does Not Actually Waterproof

Water infiltration damages structural elements, causes mould, and destroys finishes. Proper waterproofing uses multi-layer membrane systems applied to correctly prepared surfaces — not just a coat of bituminous paint.

The 7-Point Checklist Before You Hire Any Contractor in Kenya

• Do you have a portfolio of completed projects? Ask for photos, addresses, and ideally references. A company with 10+ years of experience will have documented work you can verify.
• What brands and grades of materials do you use? For painting, ask specifically — Crown Paints, Sadolin, or Basco? For waterproofing, what membrane system? Material quality directly determines longevity.
• Do you provide a written quotation and scope of work? A verbal quote is not a contract. Get a written document that specifies materials, number of coats, surface prep steps, timelines, and exclusions.
• What is your warranty or defect liability period? A confident contractor backs their work. Ask what happens if paint peels in six months or a waterproofed roof leaks in the next rainy season.
• Are your workers trained and supervised on site? Subcontracting to day labourers with no oversight is common. Find out whether the company's own trained team will be present throughout.
• What is the payment structure? Be wary of contractors demanding 80–100% upfront. A fair structure is typically 30–50% deposit, a progress payment, and a final payment on satisfactory completion.
• Can you provide a timeline with milestones? Projects without a schedule run indefinitely. A professional contractor gives you a written schedule and communicates proactively about delays.

Understanding Each Service: What Good Work Actually Looks Like

Painting: Interior and Exterior

Professional painting is 80% preparation, 20% application. The steps must include: surface cleaning, crack filling, sanding, priming (at least one coat), and a minimum of two topcoats. Exterior painting requires UV-resistant, weather-grade paint. Skipping primer is the most common shortcut — and the most damaging one.

Gypsum Ceiling and Partition Installation

Gypsum transforms spaces — from suspended ceilings with recessed lighting to full office partitions. Quality installation requires accurate metal stud framing, board joining with mesh tape and jointing compound, and a smooth skim coat finish. In kitchens and bathrooms, only moisture-resistant (green board) gypsum should be used.

Epoxy Flooring

Epoxy is ideal for showrooms, garages, commercial kitchens, and hospitals — anywhere you need a seamless, chemical-resistant, easy-to-clean surface. A proper installation involves: concrete grinding to open pores, moisture barrier, epoxy base coat, colour coat, and a protective clear topcoat. The floor must cure fully — typically 24–72 hours — before use.

Kitchen and Cabinet Repair

Cabinet restoration is a cost-effective alternative to full kitchen replacements. A skilled team can replace hinges and drawer runners, refinish cabinet faces with new laminate or paint, install new hardware, and repair warped doors. The result: a kitchen that looks new at a fraction of replacement cost.

Waterproofing

The correct system depends on the surface: flat rooftops use torch-on bitumen membrane or liquid-applied membrane systems; bathrooms use cementitious waterproofing; external walls use breathable hydrophobic coatings. A proper waterproofing job always includes a flood test before finishing layers are applied.
