An extension or renovation is the biggest thing most people will ever spend money on after the house itself. They research builders for weeks, looking for finished projects, reviews and signs that you will turn up and do it properly. Your social media is where they look first.
Here are 25 social media post ideas for builders and construction businesses, grouped by what they do for your business, plus a simple weekly plan, ready-made captions, hashtags and the mistakes to avoid.
What should a builder post on social media?
The short answer: finished projects and progress updates that show your standard, proof that you are reliable and properly insured, clear information about the work you take on and practical advice that helps people plan. Three posts a week covering that mix is enough.

Builder social media dos and don'ts
Do
- Take a photo from the same spot every week of a build
- Show your accreditations, insurance and guarantees
- Name the town or area in your posts
- Reply to comments and messages quickly, as questions turn into enquiries. Our community management service can help
- Post to your Google Business Profile as well as your social channels
- Ask every happy customer for a review
Don't
- Post photos from site that show unsafe working. Hard hats on, scaffolding tagged
- Share a customer's address or house number without permission

- Post only when things are quiet. Consistent feeds win more enquiries
- Rely on stock photos. Real photos of your own team and work are more convincing
Builder social media FAQs
What should a builder post on social media?
A mix of before and after photos, progress updates, customer reviews and practical advice on costs and planning. Aim for posts that show your work, bring in enquiries, build trust and get people talking.
How often should a builder post on social media?
Three times a week is plenty. Consistency matters more than volume, so a steady three posts a week beats ten in one week followed by silence.
Which social media platforms are best for builders?
Facebook and Google Business Profile matter most, because that is where homeowners look for local recommendations. Instagram is ideal for finished projects, and LinkedIn is worth using if you want commercial or developer work.
Do builders need professional photos?
No. Clear phone photos of real projects work better than stock images. Take one from the same spot each week so you can show the progress.
Can social media really bring in building work?
Yes. Homeowners research for weeks before choosing a builder, and a page full of finished local projects and reviews keeps you in front of them until they are ready to ask for a quote.
