The service

What sliding & french door installation is, what a visit covers and where the line is.

The short answer

Sliding and French door installation replaces or adds a patio door in an exterior wall. Sliding & French Door Installation in Los Altos is booked through pros who cover its 2 ZIP codes, in neighborhoods such as Old Los Altos, Downtown Los Altos Village, and Country Club. In Los Altos, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. Pros on NorTech set their own pricing and warranty terms, and the choice of pro is yours.

What shapes a sliding & french door installation job

These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.

Door width and number of panels
Wider openings, extra panels and taller units need stronger headers, heavier glass and more hands to set, so the width and panel count shape the whole scope.
Same opening or a new opening
Swapping a door in its existing opening is a different job from widening it or converting a window, which adds framing, a header and wall patching.
Threshold height and sill condition
The step from the floor to the patio decides how the sill pan and threshold are built.
Glass package and hardware
Safety glass, coatings, screens and multi-point locks affect what must be ordered.
Sun, wind and swing space
A door facing strong sun or wind needs different glass and seals, and a French door needs clear room to swing.
Where in Los Altos the job is
Los Altos pairs small-town character with serious Silicon Valley wealth. Many homes are original 1950s–60s ranches now being refreshed or rebuilt — owners here want careful, well-documented work that respects the property's value. Tell the pro your neighborhood or ZIP code so they know the age and style of the home.

Sliding or French: how each performs

The door style changes how much space you give up, how well it seals and what you have to maintain. Your pro can show you samples. Tap an option to compare, then add your pick to your job notes.

What is not part of sliding & french door installation

Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.

  • Any job where labor and materials together reach $1,000 or more goes to a licensed contractor, which includes most new patio door installations and any opening that is widened.
  • Structural changes to bearing walls, large headers or moving a door to a new wall are licensed-contractor work and may need a permit.
  • Decking, patio or step work that must be raised or lowered to fit the new threshold is a separate job.
  • Water damage, termite damage or mold behind the old door are scoped by the pro once they see the opening.
  • Interior and exterior painting of trim and the full door is booked as a painting service.
  • Window film, blinds and curtain hardware around the door are not included in the install.

License and permits for sliding & french door installation

Who does it

Patio door installation that widens an opening, adds a header or changes the wall around the frame is structural work done by a licensed contractor. Your pro holds that license, and it is shown on their profile.

Permits

A permit is commonly required when an opening is enlarged or moved, and often when an exterior wall is altered. A same-size swap in an existing frame is often exempt, but check with your building department.

Check your pro

Look at the pro's license on their NorTech profile and ask whether a permit is needed. Keep the final inspection record with your home paperwork.

Plan your visit

How booking works, how to get ready, and what to expect where you live.

How booking sliding & french door installation works

  1. Say what needs doing

    Add your ZIP and a few words about the job.

  2. Compare pros near you

    Each pro sets their own price and warranty. NorTech does not pick for you.

  3. Book the pro you pick

    Add photos and details on their page. Your card is held and only charged after the work and the photos.

  4. Photos and a warranty

    Your pro backs the work with a workmanship warranty — if covered work is not right, your pro makes it right, free.

Before you book sliding & french door installation

Quick things that save a trip. Tick them off as you go; none of it is required to book.

0/7
Let’s get you readyTap a card when you have done it.

Measure the opening in three places

Measure width and height at both sides and the center, and note whether the door opens left or right from outside. Your pro takes the final measure, but numbers help them quote.

Look for rot at the sill

Press on the bottom corners of the frame and the floor at the threshold. Soft wood, stains or a musty smell are worth pointing out, since your pro decides whether the opening needs repair before the new door goes in.

Choose which way it swings

Stand outside and decide whether the door should swing in or out, and which hinge side. Furniture, porch rails and walkways decide what works.

Consider security

Ask about multi-point locks, laminated glass and a bar or pin for sliders. Entry points on the ground floor deserve the best hardware.

Plan for an open wall

The opening is exposed for hours. Move furniture, pets and plants away, and plan for weather and for your home being open to the yard.

Ask for the product paperwork

Keep the door labels and warranty sheets, which show glass type, rating and sizes. You will need them for insurance and any future glass replacement.

Say where in Los Altos you are

Add your neighborhood, for example Old Los Altos, Downtown Los Altos Village, and Country Club, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

How where you live changes sliding & french door installation

Add your ZIP in the booking card at the top to see weather alerts and the season for your area.

Hot sun and cold winters need different glass and seals

The Bay Area has dry summers and a wet winter, and the weather changes a lot between the foggy coast and the hot inland valleys. A big sheet of glass facing south or west gains heat in summer and fades floors and furniture, so a low solar gain coating helps. In freezing climates a poorly sealed slider is a cold draft and a place for frost to form on the track.

Fill in the blanks first. The note goes to the pro you choose.

Best time to book sliding & french door installation

Spring Mar to MaySummer Jun to AugFall Sep to Nov

A patio door leaves a very large opening exposed during the swap, so mild and dry weather is easiest on you and on the framing. Winter installs can be done, but cold air and wet snow move through the house until the unit is closed. In Los Altos, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain.
