7 Best Main Door and Security Door Contractors in Singapore (2026)

Choosing an entrance for a flat, condominium or landed home usually means deciding on a main door, a metal gate or both, and then finding a contractor who can supply and install them properly. This page collects seven Singapore companies whose own websites list main doors, metal gates or related entrance products, with 2026 signs of activity. Some focus on laminate or fire-rated doors, others on mild steel and stainless steel gates, and a few cover grilles and locks as well. Read each profile for what the company itself publishes, compare the product lists with your own needs, and ask each firm for a written quotation before you commit.

HDDoor is a main door and gate specialist whose website lists laminate main doors in several finishes, including fire-rated laminate, 3D laminate, single-tone and double-tone styles, plus stainless steel line-mix and groove-line designs. Its gate range, as published, covers mild steel, privacy, pet-safety, mesh, laser-cut and tempered glass options, along with customised gates. The company also lists digital locks from brands such as Hafele, Aqara and Igloohome, so a door, gate and lock can be discussed together. The site states that it holds ISO 9001:2015 certification and shows bizSAFE and contractor badges; those are the company's own statements, not LocalRank's. It shows a showroom in Grantral Mall, and enquiries can go through its contact page, phone or sales email.

SG Gate Door Window, operated by SG GDW Supplies, publishes a broad catalogue aimed at flat and home owners. Its site lists HDB main doors and gates, BTO gates, main doors, fire-rated doors, aluminium and sliding doors, and a metal gate range covering mild steel, stainless steel and wrought iron, including pet-friendly and cat-proof designs. Window grilles and several digital lock brands appear alongside them, which suits owners fitting out a new unit in one go. The company describes two experience centres, one on the north side at Woodlands and one on the west side at Bukit Batok, so you can see samples before ordering. Its site offers a contact page, a sales email and a WhatsApp link for quotation requests.

Ho Ho Door presents itself as a long-running Singapore firm, saying on its site that it has operated since 1976. Its catalogue lists an HDB main door under wooden doors, alongside fire-rated, bedroom and laminate doors, and a gate section covering wrought iron, mild steel, aluminium and driveway gates. Aluminium doors, bifold and sliding doors, window grilles and digital locks are also listed, so one contractor can cover several openings in a home. The website describes the business as an HDB licensed and BCA registered contractor; that is its own wording, and the licence number appears with two slightly different spellings on the page, so ask for the paperwork. Enquiries are by the telephone and mobile numbers printed on the site.

Brooklynz Stainless Steel is a metal works company whose website groups its entrance products under a doors and gates menu. That menu lists metal gates with a repair service, mild steel gates, stainless steel gates, automatic gates and roller shutter doors, including fire-rated shutter maintenance as the site words it. The same site also covers railings, bollards, fencing and staircases, which helps if a gate has to match other metalwork around a landed property or commercial unit. It lists an address in Bedok North and a contact page, and says its number takes WhatsApp calls or messages only. It does not list main doors or security doors as separate products, so ask what it can make before sending measurements and photos for a quote.

Legate is a home improvement supplier whose website lists metal gates, with footer links for HDB and condo gates, among a wider range of invisible grilles, aluminium grilles, mozzie grilles, roller blinds, awnings, window film and landed property autogates. For an owner who wants entrance gates and window protection handled by one company, that mix is the appeal. The site shows a showroom inside T-Space in Tampines, a sales email and two telephone numbers, so a visit to look at samples is possible before committing. It does not list main doors or security doors in its published product list, so treat it as a gate and grille option and confirm the exact scope when you enquire. Check the quotation lists materials, finishes and installation.

Pang Giap, registered on its site as Pang Giap (211) Pte Ltd, lists HDB gates in swing, sliding and folding formats, plus driveway and fence gates and louvre gates. Beyond gates, its catalogue includes window grilles, pot belly and cat-proof slim grilles, railings, soundproof doors and windows, glass doors and aluminium doors, so a single quotation could span a whole unit. The site says it serves HDB flats, condominiums, landed homes and commercial and industrial properties. It does not list main doors as a product, so ask directly whether it can supply the entrance door you have in mind. Its pages carry an email, a telephone number and a WhatsApp link, and the site was updated in late September 2026.

Window-Grille-Door.com, titled Windows, Grilles and Doors Singapore on its site, lists mild steel, iron, automatic and fence gates under its grilles and gates menu, alongside aluminium grilles and a door range covering sliding, swing, folding and bi-fold styles. Its contact page asks for the unit type, with HDB BTO, condo, landed and office options, and offers a quotation request and a site visit by appointment. The company states that its contracting partners are BCA registered window contractors and HDB registered renovation contractors; that is its own statement and relates to its partners, so ask exactly who will do the work. It gives an office address in the Senoko area and a phone and WhatsApp number but no public email address.
