Many people assume that door installation is a quick, straightforward process. But in reality, it’s one of the most common areas where major (and expensive) mistakes happen — from incorrect measurements to poor installation. These mistakes can lead to drafts, poor insulation, crooked doors, and unexpected repair costs.
If you want your new door to function properly for years, it’s important to approach the installation with careful planning and the right team. In this article, we’ll explain how to avoid common traps, what to watch for, and how to choose professionals who do the job right.
Accurate Measurements Are Everything
It all starts with the right measurements — width, height, and depth of the opening. Measurements must be taken in multiple spots, especially if the walls or floor aren’t perfectly level.
Even a few millimeters off can cause the door to stick, leave gaps, or fail to close correctly.
Be Careful Who You Trust
In many companies, the person who comes to take measurements is actually a sales rep, not a technician. They’ll push you to leave a deposit right away, claiming there's a “special one-day deal.”
These are not honest consultations — they’re sales tactics. And sadly, many customers end up overpaying 2–3 times more than necessary just because they fell for the pitch.
Our Approach: No Pressure, Just Real Advice
With us, the person who visits your home is a real technician, not a salesperson. They’ll explain installation methods, materials, possible adjustments, and recommend the best option based on your actual opening and your goals — not on sales quotas.
Always Compare Multiple Quotes
Don’t settle for the first offer. Request 2–3 estimates from different companies, compare the details, and ask clear questions. If someone avoids specifics — that’s a red flag.
Check Licenses and Insurance
A trustworthy company should have:
- A valid license for door installation
- Liability insurance
- Written warranty obligations
If these are missing — walk away. These documents protect your money and your home.
Who Will Actually Install the Door?
What most homeowners don’t know: many companies use subcontractors for installation. Subcontractors work on fixed rates and often rush to get to the next job. This leads to:
- Cheap foam
- No flashing or waterproofing
- Loose or uneven frames
- Gaps and drafts
And worst of all — once you’ve paid the company, the subcontractor is long gone, and you’re left with the issues.
Lifetime Warranty? Read the Fine Print
A lot of companies advertise “lifetime warranties” — but most of them are full of limitations and exclusions. When a problem arises, they’ll find ways to avoid responsibility.
The real warranty is a job done right the first time, by people who stand behind their work.
Signs of a True Professional
When a technician shows up, observe how they behave:
- Do they have their own professional tools?
- Is their van clean and organized?
- Do they treat your home with care?
- Are their answers clear and confident?
Ask them:
- How do you install the door?
- What materials do you use?
- Will you flash the opening?
- Do you use a laser level?
If they answer confidently and directly — you’re in good hands.
How We Install Doors: Our Standards
- Prep the opening — clean, level, and apply flashing tape
- Check alignment — always with a laser level, never just by eye
- Install with care — shim every 24–25 inches and use screws hidden behind the weatherstrip
- Insulate properly — use low-expansion foam to avoid frame warping
- Seal it right — with flashing tape and caulk for a waterproof finish
Proper door installation is a skilled and responsible job. Don’t trust just anyone with it. Take your time, ask smart questions, and choose professionals who care about the details. That’s the only way to guarantee a door that will last for years.
