Key Elements of a Strong Cover Letter
Start with your full name, phone number, email, and LinkedIn or portfolio link when relevant. Include Mason's hiring contact and the internship title so readers can match your letter to the right opening.
Lead with a brief sentence that explains why you want this internship at Mason and what you bring. Keep it specific to the program, team, or project to show genuine interest.
Focus on 2 or 3 examples that connect class projects, volunteer work, or part-time roles to the internship responsibilities. Use concrete results or what you learned to show you can contribute from day one.
End with a short statement that expresses gratitude and asks for a next step, such as an interview or follow-up. Provide your availability and invite them to contact you for more details.
Cover Letter Structure
1. Header
Include your name, city, phone, email, and a LinkedIn or portfolio link if you have one. Below that, add the date, Mason's department or hiring manager name if known, and the internship title you are applying for.
2. Greeting
Address the letter to the hiring manager when possible, using their name and title. If you cannot find a name, use a specific department greeting such as "Dear Mason Internship Team" to show you researched the role.
3. Opening Paragraph
Write a concise opening paragraph that states the internship you are applying for and why you want it at Mason. Mention one clear reason you are a good fit and what excites you about the opportunity.
4. Body Paragraph(s)
Use one or two short paragraphs to highlight 2 or 3 relevant experiences or skills, focusing on outcomes and what you learned. Tie each point directly to the internship duties so the reviewer sees how you will add value.
5. Closing Paragraph
Finish with a polite closing paragraph that thanks the reader for their time and asks for the opportunity to discuss your fit further. Offer your availability for an interview and mention you will follow up if appropriate.
6. Signature
Use a professional sign-off such as "Sincerely" or "Best regards" followed by your full name. If you submitted the letter electronically, include your contact details again under your name.
Dos and Don'ts
Customize the letter for the specific Mason internship and mention one detail about the team or program. This shows you did your research and care about the fit.
Keep the letter to one page and use short paragraphs to make it easy to scan. Busy reviewers appreciate clarity and brevity.
Use concrete examples from coursework, projects, or part-time work to show relevant skills. Briefly describe outcomes or what you learned to make your case stronger.
Match keywords from the internship posting in your letter where they naturally fit. This helps reviewers see the direct connection between your background and the role.
Proofread carefully and ask a friend or mentor to review your letter before sending it. Small typos can distract from your qualifications.
Do not copy your entire resume into the cover letter or repeat every bullet point. Instead, expand on one or two highlights that matter most for the internship.
Avoid vague claims like "hard worker" without examples that show how you worked hard. Concrete results and brief stories are more persuasive.
Do not use overly casual language or slang when addressing Mason staff. Keep the tone professional while still showing personality.
Do not apply generic greetings like "To whom it may concern" when you can find a department name or hiring contact. A specific greeting reads as more thoughtful.
Avoid long paragraphs that bury your main points and make the letter hard to read. Short paragraphs help your key skills stand out.
Common Mistakes to Avoid
Using a template without customizing it for the Mason internship can make you seem uninterested. Tailor one or two lines to the program to improve your chances.
Oversharing unrelated experiences makes the letter unfocused and long. Stick to examples that directly connect to the internship responsibilities.
Failing to show what you learned from each experience leaves claims unsupported. Briefly note outcomes or skills gained to give your examples weight.
Neglecting to include contact information in the header can slow down follow up. Make it easy for the reviewer to reach you by listing phone and email clearly.
Practical Writing Tips & Customization Guide
Open with a specific reason you want this Mason internship, such as a course or professor that inspired you. Specificity helps you stand out from generic applicants.
If you lack direct experience, highlight related coursework or project outcomes and explain how they prepare you for the internship. Focus on transferable skills and eagerness to learn.
Keep sentences short and use active verbs to make your achievements clearer and more engaging. This makes your letter feel dynamic and confident.
Send a brief, polite follow-up email about one week after applying if you have not heard back. A short follow-up can remind the hiring team and show your continued interest.
Cover Letter Examples
Example 1 — Recent Graduate (Masonry Internship)
Hello Ms.
I’m a civil engineering student at State Tech finishing my junior year and I’m applying for the Summer Masonry Internship at StoneWorks. Last summer I completed a 12-week field placement where I assisted on a 4-building restoration project: I measured and cut 240 sq ft of brick veneer, prepared mortar mixes to spec, and helped reduce material waste by 15% through tighter layout planning.
I also logged daily safety checks and maintained tools for a crew of five. I want to bring hands-on skills, strong math ability (A in construction materials), and a safety-first mindset to StoneWorks’ historic restoration team.
I am available from June 1–Aug 15 and can travel to your downtown sites. I’ve attached a photo log and contact info for my site supervisor, Mark Ellis.
Thank you for considering my application; I’d welcome a short site visit to discuss how I can contribute to your summer projects.
What makes this effective:
- •Specific metrics (240 sq ft, 15% waste reduction).
- •Clear availability and supporting documents.
- •Links academic skills (materials course) to field work.
Cover Letter Examples
Example 2 — Career Changer (Landscaper to Masonry Intern)
Dear Mr.
After five years as a lead landscaper managing irrigation and hardscape installs, I’m shifting fully into masonry and applying for the Masonry Intern role at Brick & Beam Co. On projects averaging $8,000 I supervised 2–4 workers, read site plans, and used saws and grinders daily.
I completed a 40-hour OSHA 10 course last month and built a DIY garden wall that withstood two winters with no repair.
I’m especially interested in Brick & Beam’s thin-brick veneer work because I have experience matching stone patterns and setting elevations within 1/8 inch. I can start part-time March–May and full-time in June.
I’d welcome the opportunity to demonstrate trowel technique on a short trial task.
Sincerely, J.
What makes this effective:
- •Transferable skills quantified (project averages $8,000, crew size).
- •Shows safety training and precise measurement ability.
- •Offers a low-risk trial (trial task), which appeals to hiring managers.
Cover Letter Examples
Example 3 — Experienced Professional Seeking Internship/Apprenticeship
Hi Ms.
I bring four years as a mason’s assistant on commercial sites and I’m applying for the Apprentice Internship at Harbor Construction. I’ve laid over 3,000 sq ft of brick and block, executed waterproofing on five storefront projects, and coordinated deliveries that kept schedules on track—cutting average downtime by 20% last season.
I’m certified in scaffold safety and completed a certificate in masonry restoration techniques.
At Harbor, I want to move from an assistant role to taking responsibility for layout and mortar proportioning under supervision. I’m comfortable reading CAD-derived plans and working on multi-trade crews.
I can start immediately and have references from two foremen who can confirm my track record.
Thanks for your time; I’d like to meet on site to review recent Harbor projects and show my portfolio.
What makes this effective:
- •Strong, quantifiable achievements (3,000 sq ft, 20% downtime reduction).
- •Clear growth goal (layout responsibility) and relevant certifications.
- •Offers evidence (foremen references, portfolio) to back claims.
