Modular home installation: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering modular home installation

You set factory-built sections on prepared foundations and finish the joins, roofs and trim on site. Customers rely on you to check the foundation, plan the crane day and leave a home that is sealed, connected and inspected.

What customers ask

  • Who checks the foundation, and what tolerance does the manufacturer allow?
  • How long will the crane day take, and what happens if weather stops it?
  • Who does the seams, roof joints and trim, and when will they be done?
  • Who handles the utility tie-ins and the inspections?
  • Can you show me a home you have set on a similar site?
  • What warranty covers the set and what covers the factory build?

How to win the job

  • On the first call, ask for the manufacturer, the module count, the site access and the foundation status, then say what you need to confirm before the set
  • Walk the site and check the crane path, the overhead lines and the setting area before you bid
  • Put the foundation check, the crane day, the seam work and the utility tie-ins in the quote as separate lines
  • Share a written crane plan and a set day schedule with the customer and the transport company
  • Show photos of seam and roof joint work on past sets, so the customer can see the finish they will get
  • Tell the customer in writing what remains after the set and who finishes it

What to put on your profile

  • Post photos of sets with the crane, the module count and the finished seams labeled
  • List the manufacturers you install and the foundation types you have set on
  • Show your seam, roof joint and trim finish work from completed homes
  • State the sites and distances you cover and whether you coordinate the utility trades

Follow-up that helps the customer

  • Offer a post-set walk-through to check the doors, windows and seams after the first season
  • Suggest a foundation check after the first winter or heavy rain, since settling affects the fit of doors and seams
  • Offer to keep the set records, the manufacturer's manual and the warranty papers on file for the owner

Licenses and permits

Installers usually need to hold the right contractor or installer registration, and the utility tie-ins must be done by licensed trades. Many areas also require a permit for the set and the connections. Check with your state and local licensing agencies and your local building department before you take a modular job.

Questions

What do I do if the foundation is out of level on the set day?

Stop the set and do not force the module onto the bearing points. Measure and document the out-of-level condition, then have the foundation corrected before the set is resumed.

Who is responsible for a seam that leaks after the set?

The contract should say. Many installers finish the seams and roof joints under their own warranty, while the manufacturer covers defects in the factory build. Put the split in writing before the set day.
