How to Choose a Residential Window Cleaning Company in Laval

The best residential window cleaning company in Laval is the one whose quote states exactly what is washed, how, and what costs extra. Altara is a Greater Montréal residential window cleaning company that serves Laval homes with a published flat rate for exterior cleaning (glass, frames and sills, washed with deionized water on a water-fed pole), and it has cleaned more than 7,800 homes.

What a fair quote should spell out

Quotes for the same house can differ widely because companies include different things. Before comparing prices, line up the scope.

QuestionWhy it matters
Exterior only, or inside and outside?Interior glass is often priced separately
Are screens and tracks included?These are commonly add-ons
How is the price set?By window count or tier is easier to compare than an hourly estimate
How high can the crew reach?Pole reach and ladder use change the price on two- and three-storey homes
What if there are streaks?A written re-clean window protects you

How Altara handles each point

The flat rate is for the exterior, and you pick the window-count tier online at the pricing page. Interior glass, screen removal and washing, and track cleaning are optional add-ons. Skylights, solariums and heavy mineral stains are quoted separately. The pole reaches up to three storeys from the ground, and taller or hard-access homes get a site visit first. If you report a streak within 24 hours, the crew returns to clean it at no charge.

Insurance, licensing and proof

Ask every company for current proof of the coverage it claims, and get it in writing. Altara is not insured, bonded or CNESST registered, so homeowners who require those should ask each company for a certificate before booking.

Red flags when comparing

  • A price with no list of what is included
  • No mention of how streaks are handled
  • Reviews or ratings you cannot trace to a real listing
  • Pressure to book the same day without a written quote

Timing for Laval homes

Exterior cleaning runs from about March to November. Spring clears winter salt film and pollen, and fall clears leaf grit before the cold. Interior add-ons can be done all year. Quarterly service carries a 10% discount, bi-monthly 15% and monthly 20%.
